This NAD C315BEE was buzzing on arrival due to a defective Main Capacitor. I upgraded both to Chemicon KMH series 105C rated caps. Many of the original JH branded Electrolytic Caps were also testing bad, so I upgraded the audio capacitors to Bipolar nichicon and ELNA, and I upgraded the Power Supply caps to mostly 105C rated nichicon, ELNA, etc. For added versatility, I have repurposed the (fixed line level) Tape Output RCA Jacks to be (variable level) Preamp Outputs suitable for a powered Subwoofer, external Power Amp, etc. Im also including a new 6-button learning remote programmed for Mute On/Off, Volume Up/Down, and 3 Input Selects DISC, CD, and AUX. I can reprogram as requested. Cosmetically, this unit is in excellent shape inside and out except for some dings on the top/side cover. Please see photos. Full refund within 60 days. Buyer pays return shipping. Please message me with any questions, corrections, etc. ******* Chapter Two ******* The NAD C315BEE is a surprisingly powerful little Beast disguised as the entry level NAD C series amplifier. Rated at 40 NAD watts per channel, the 45 Volt Main Rails and 10,000uF Main Caps provide plenty of IHF Power as well. While the reviewers are quite complimentary of this model, some have mentioned their desire for Preamp Outputs. VOILA!! It should be noted that the Standby Mode draws similar power and generates similar heat to the ON Mode. I recommend turning OFF the Main Switch on the Rear Panel when not in use.

In typical fashion, this NAD 7220PE arrived with shorted Output Transistors in one Power Amp channel. Fortunately, the fuses blew before any driver transistors were damaged, so this unit is otherwise all original silicon. It is the 3220PE Power Envelope version of the 3020e integrated amplifier and the 4220 tuner in one package. I Souped Up this unit by upgrading the output transistors in both channels to Toshiba C5200/A1943 complementary pairs which are intended for 100W high fidelity amplifiers. NAD uses them in their C series amps. They can easy handle and take full advantage of the higher +/-40V Power Envelope Rails. I also increased the Main Caps from 4700uF to 6800uF 105C Chemicon for the same extra Punch as the 7225PE. I replaced all of the electrolytic caps in the Integrated Amplifier and Tuner Audio sections. The audio caps have been upgraded to ELNA CE Bipolar and nichicon Fine Gold Audio along with Vishay Film in the Tone Control section. The new power supply caps are Chemicon and Rubycon. I have rewired the Tape Out jacks on this 7220PE to be the variable Preamp Outputs for use with a powered subwoofer, additional power amp, etc. These are the same preamp outputs as on the 7225PE and allow these units to be used in a larger system as a Phono Preamp and/or Preamp/Tuner. I have been testing this unit with Boston HD-5 bookshelf speakers and a Velodyne subwoofer, and it sounds great. Finally, I upgraded the ultra sensitive Bias trimpots to multi turn equivalents for more accurate and more stable adjustment. Cosmetically, this 7220PE is in excellent condition except for some scratches on the top cover. Please see photos. Full refund within 60 days. Buyer pays return shipping. Please message me with any questions, corrections, etc. ******* Chapter Two ******* The 7220PE is a 3020_like receiver in that it is based on the same all-discrete transistor phono preamp, control amp, and power amp designs as the earlier 3020A. It is also rather elegant in that it has two independent power transformers and power supplies, one for the analog integrated amplifier section and the other for the digital tuners. It is literally an integrated amp with a tuner on top.

This NAD 302 was originally wired for 240VAC, but Ive rewired it per the service manual for 120VAC and replaced the Power Plug with a USA version. The Green Power button was missing and has been replaced with a Black one. This amp arrived DOA due to multiple shorted capacitors in the preamp power supply, so I replaced ALL of the electrolytics. The Audio Coupling caps have all been upgraded to Bipolar nichicon MUSE BP, VP, and ELNA CE-BP. The Power Supply caps have been upgraded to higher voltage/temp rated nichicon, Chemicon, and Panasonic. The large Main Caps are 6800uF 50V 105C KMD Chemicon. The Bias trimpots have been upgraded to multi turn equivalents for more accurate adjustments (30 mV) that are less likely to drift. The Offsets have been adjusted to 0 mV. The switches, pots, and chassis have all been cleaned. The RCA Jacks have been re-soldered, along with much of the board. Cosmetically, this 302 is in great condition. A couple of scratches on the front panel and top cover. Please see photos. Full refund within 60 days. Buyer pays return shipping. Please message me with any questions, corrections, etc. ******* Chapter Two ******* The NAD 302 is a well refined and souped-up version of the early 3020 designs with these added features; - a Tone Defeat switch that electrically removes the Bass and Treble controls. Remember the 3020B vs. 3120 debates? The 302 can be configured as either. - an all electronic Power On/Off Mute circuit for use with remote Power Strips, etc. - an Impedance switch to select low or high Main Voltage Rails for the Power Amp - higher voltage output transistors - larger Main Caps - additional inputs and 2 tape outputs. - a heftier Heat Sink arrangement for the Power Amp components - a more traditional chassis style with RCA jacks that face out instead of up. From the schematic point of view, the 302 circuit topology includes the same all discrete 4-transistor Phono Preamp used throughout the NAD product line from the 3020A to the Monitor Series, combined with the Control Amp and Power Amp topologies from the early 3020 versions. In the 4 ohm (Low) position, the Impedance switch supplies the same +/- 30V Main Rails to the same Power Amp design of the original 3020 Series 20. In the 8 ohm (High) position, the Main Rails are increased to +/- 37V, providing additional power and dynamic range; 25WPC RMS, 40WPC IHF. IMO, unless the unit is overheating, the High position should be used for maximum performance.

This fully recapped and restored 3020B looks, feels, and sounds like new (or better)! It arrived with a nasty HUM due to failing capacitors in the Preamp Power supply. It also had several damaged RCA Jacks, so I replaced the full Input set of 6 with new color coded jacks. The Red Jacks are a bit shorter than the White, but I still like it! The upgraded Audio Caps are Vishay Film, nichicon MUSE BP, Fine Gold and ELNA. The Main Caps have been upgraded from 4700uf to 6800uF 105C Chemicon for an extra IHF Punch. The Offset trimpots have been upgraded to multi turn equivalents for better accuracy and stability. The Biases have been re-calibrated with new RX resistors installed as required. Cosmetically, it is overall as nice as Ive seen. Minor imperfections. Please see photos. Full refund within 60 days. Buyer pays return shipping. Please message me with any questions, corrections, etc. ******* Chapter Two ******* AFAIK, the 3020B and 3120 are the last versions of the 3020x with vertical RCA Jacks. They also have Banana Jack Speaker outputs.They are all discrete and have the low-noise Phono Preamp for MC/MM cartridges that NAD used for years thereafter. BTW, the 3020 LAB IN RCA Jacks can also be used as Preamp Outputs for a Powered Subwoofer, etc. Adding a Sub can be life changing.

Both units recently serviced & fully working C350 is better than new -- its fully re-capped and restored, including the hard-to-find 22000uF/63V supply caps (installed German-made Mundorf M-lytics). Premium capacitors throughout, all Panasonic FC/FM and Nichicon FG/ES. Problematic standby relay has been replaced too. Freshly biased/aligned. This is an all-discrete amp (no chips in the signal path) with incredible specs and NADs impedance sensing circuit that adjusts output current for whatever loudspeaker impedance you hook up. Sound is pristine, and the amp drives complex speaker loads with great stability and no overheating. Includes short RCA jumper cables for the pre-out/power-in jacks. C420 is all-original, recently checked and working well. Still has original Elna capacitors throughout, which are all tested good. Includes: - Original C350 remote, which controls both units (volume knob on the C350 is motorized) - RCA patch cables for pre out/power in on the C350 and for connecting the C420 to the C350 Does not include AM or FM antennas for the tuner Some scratches on the cases of both units -- see pictures Local pickup welcome if you are near Philadelphia PA.

Unit had one channel out. Repaired channel. Partial recap of all out of spec caps. Bias, DC offset, and meters adjusted to factory specs. All controls cleaned and tested. All functions tested working. Cosmetically 7 out of 10.

This NAD 3020 Series 20 Version 1 Amplifier arrived with blown fuses due to shorted driver and output transistors in one of the Power Amp channels. I have replaced the driver and output transistor pairs of BOTH channels with matched quad sets so that both channels are electrically identical. The Output Transistors have been mounted with ceramic thermal washers that do not require grease. They look much better, too. The Power Supply caps have all been upgraded from 35V to 50V nichicon, Rubycon, Chemicon and Panasonic. The 4 Main caps are 50V nichicon FW Gold. The Phono Preamp input caps are nichicon MUSE Bipolar. The other audio caps have been upgraded to nichicon Fine Gold and ELNA. Ive upgraded the Power Switch to a hefty 7 amp version which should last forever. I have also upgraded the Power Amp Offset adjustments to multi-turn trimmers which are more precise and less likely to drift. I have re-soldered the rear RCA and DIN jacks, the front switches, controls, and headphone jack, and much of the main board itself. I then cleaned the solder side with Flux Remover and Alcohol. It looks better than new. Cosmetically, this unit is is excellent condition but with minor scratches on top. Please see photos. Yes, this 3020 sounds exceptional, and has been upgraded to do so for many years to come. Full refund within 60 days. Buyer pays return shipping. Please message me with any questions, corrections, etc. ******* Chapter Two ******* This NAD 3020 is an original Series 20 Version 1 with the 5 transistor phono preamp and the 3 transistor control preamp. It is the ONLY 3020 version without the series muting FETs known for their Welcome Hum and other various distortions. AFAIK, this is also the version with the mystical layout artwork error that improves the sound quality ??? Please advise. Version 1 can be identified by the separate Power Supply board mounted on the back panel, the Power transformer mounted on a bottom plate, and the 4 Main Caps located in the front left of the circuit board. FWIW, the later 3020 Series 20 Version 2 had a 6 transistor phono preamp and the 4 transistor control preamp topology used thereafter. The 3020A and thereafter then settled on a 4 transistor phono preamp, including a low noise version for MC cartridges on some units.

I won’t go into all the tech specs here as if you’re looking at this listing you likely know it already. Suffice to say this is a glorious beast of a power amp. 150 watts continuous (NOT peak) per channel at 4/6/8?, and will do 400 in Bridged mono mode!! This was used to drive my fronts pre-outed in a home theatre set up, when playing music in stereo mode the sound is amazing. Sadly with the current economic crisis I have removed this from my set up and am letting my home theatre receiver power my fronts. Very sad face. This was professionally recapped some six months ago, and has just been fully serviced ready for sale by MJ Stills Pro Audio, Sussex. The interior of the unit is pristine. Both recapping and servicing were a considerable expense. This is NOT simply an old second hand item and that is reflected in the price. There is some visible scuffing on the front and top, but no deep scratches, and is in excellent condition for such a classic piece. This is an extremely heavy item, and sending fully insured by special delivery is reflected in the postage cost. I’m happy for this to be collected from Brighton, East Sussex if required. DO NOT BID UNLESS YOU HAVE EXCELLENT FEEDBACK OVER A GOOD NUMBER OF YEARS ON EBAY. I WILL CHECK FEEDBACK OF ALL BIDDERS, SO IF YOU ARE UNSURE THAT YOU MEET THIS REQUIREMENT THEN PLEASE MESSAGE ME BEFORE BIDDING. YOU WILL SEE THAT MY FEEDBACK AS A SELLER IS EXCELLENT.

This unit was in need of a new Power Switch and a new set of Muting FETs. It is otherwise all original except as upgraded below; I have updated the mute ON/OFF circuitry to match that of the 3225PE. See last photo. This allowed me to replace the original 3 Amp Power switch with a more robust 7 Amp switch that should last forever. I have upgraded all of the Electrolytic Capacitors. The Power Supply caps are nichicon, Chemicon, and Panasonic. The Phono Preamp and Control Preamp audio caps are ELNA. The Phono Input coupling caps are ELNA SILMIC II Bipolar. The Power Amp caps are nichicon Gold. For added versatility, I have repurposed the (fixed line level) Tape Output RCA Jacks to be the (variable level) Preamp Outputs suitable for a powered Subwoofer, external Power Amp, etc. They are equivalent to the Preamp Outputs on the 3225PE which allows this unit to be used as a Preamp only. Cosmetically, this unit is in great shape inside and out except for a bunch of marks on the top/side cover. Please see photos. Feel free to message me with any questions, corrections, comments, etc. ******* Chapter Two ******* Whenever I acquire an NAD 3220PE with all of the original Power Amp transistors intact, I prefer to preserve and protect them by removing two fuses to disable the PE Supply, effectively re-configuring the unit as a 3020e. This reduces the Main Rails to 60V and more accurately emulates the operation and performance of the iconic 3020 Power Amp section while also staying within the specified safe area of the output transistors, making them less likely to fail. While this does reduce the specified IHF Dynamic Power, I have compensated somewhat on this unit by Beefing_Up the RMS Performance with upgraded Main Caps, going up from 4700uf to 6800uf Chemicon. Ill also be happy to reinstall the fuses on request.

This NAD 7000 was damaged during shipping. The Balance and Volume controls were pushed upward and in towards the chassis. I was able to straighten things out such that the controls turn smoothly and operate properly, but the motor clutch for the remote control volume operation is no longer functioning properly. Im including a new 6-button basic learning remote programmed for Power On/Off, Mute (Low Level) On/Off, Channel Search Up/Down, Tape_1, and Tape_2 input selects. This will provide three remote source selections; Tape_1, Tape_2, and the selected input (Phono, Tuner, CD, or Video). If a remote volume control is not a requirement for you, then this unit is a great deal for a top tier vintage NAD Monitor Series Receiver / Amplifier / Phono Preamp / Tuner that has been restored and recapped as follows; 1) Upgrade all of the Electrolytic Capacitors in the Integrated Amplifier and Power Supply sections. The audio coupling caps are nichicon MUSE Bipolar and Meritek Film. The Power Envelope 80V caps are nichicon and the 50V Main Capacitors are United Chemicon. The other caps are Rubycon, ELNA, Panasonic, etc. 2) Replace overheating resistors. Two of the 1/4 W resistors in the power amp are specified on the schematic to be 1/2 W and actually dissipate over 1/4 W. They get so hot that theyve discolored the PC board. Ive replaced them with 1W metal film resistors and elevated them away from the PC board surface. 3) Disable Soft clipping. This circuitry is another hot spot on the 3240PE/7240PE and 7000 main boards that also involves a small coax cable with 140 VDC across it; rather dangerous for the unsuspecting. The underrated components have also discolored the PC board and deteriorated themselves. The soft clipping circuit actually limits the amplitude of the INPUT signal going to the Power Amp in a graceful way based on the Main Rail voltage. I dont really see the benefit for this model, given that the IHF Power rating is 160 WPC. I have therefore disconnected the 140 V coax and disabled the soft clipping operation. No more overheating or shock potential. 4) Upgrade the Bias controls to multi-turn trimpots. They provide more precise adjustments that are also less likely to drift. 5) Clean and Deoxit the controls and switches to operate smoothly and quietly. Cosmetically, this unit is in great condition inside and out. Surface scratches on top and an imperfect front panel corner. Please see photos. Full refund within 60 days. Buyer pays return shipping. Feel free to message me with any questions. ******* Chapter Two ******* IMO, the 7000 is the sweet spot of the NAD receivers from that era. It is essentially the 1600 Monitor Series Preamp/Tuner combined with the Power Envelope Power Amplifier from the 3240PE/7240PE. It provides 40 WPC RMS with 6 dB of headroom for up to 160 WPC IHF, all with a Power Transformer that is relatively small and lightweight. Quite an impressive design with an effortless, spectacular sound. The Phono Preamp is the same all discrete 4-transistor topology that NAD used for years beginning with the 3020A and continuing into the Monitor Series. The 7000 has the low noise version with the MM/MC gain select switch. The tuner section is noteworthy for its superior FM sound quality and switchable FM noise reduction (FM Blend). Even the AM sounds good.

This is a service only listing to Restore and Re Cap one NAD 3140 amplifier that YOU send to me. The shipping charge is for the return trip back to you in the same box sent. Installation of four Banana Jack/Binding Posts for SPEAKER_A are included.

This NAD 3140 has been upgraded and custom retrofitted to eliminate the thermal issues that plagued this model throughout its production. There are overheating 2-watt resistors in the preamp power supply that bake (and prematurely deteriorate) the surrounding purple electrolytic caps to a golden brown. I have relocated these resistors on terminal strips above and away from the other components. See the last photo. A second set of overheating resistors that supply the front panel LEDs (of all things!) has been eliminated by upgrading the ancient LEDs with much lower power versions. The soft clipping circuit has been updated to the latest Zener diode version (per the Service Bulletin) but with four 1 watt zeners instead of two 1/2 watt zeners to reduce the overheating that was occurring in that area as well. I have installed four Banana Jack/Binding Posts for SPEAKER_A in addition to the original Spring Terminals. The standard 3/4 spacing accommodates paired plugs. I have replaced ALL of the electrolytic capacitors. The four 4700uF Main Caps have been upgraded from 50V to 63V since they are actually charging up to 51V in this unit (NAD was notorious for this). The other power supply caps have been upgraded to higher voltage and/or 105C temp ratings. The audio caps have been upgraded to ELNA, nichicon MUSE BP, FW, and Fine Gold Audio as well as Vishay Film in the Bass_EQ and Control amps. I also replaced many of the 0.1 disc caps that were looking old and baked and worn with new multi-layer ceramics. I have upgraded the 4 very sensitive Bias and Offset adjustments to multi-turn trimpots. They allow a more precise adjustment that is less likely to drift or be accidentally disturbed. I have cleaned the switches with Deoxit D5 and cleaned/lubed the pots with Deoxit Fader F5. Cosmetically, this unit is in good condition. It has a few scrapes on the top cover and the front panel. Please see photos. Full refund within 60 days. Buyer pays return shipping. Please message me with any questions, corrections, etc. ******* Chapter TWO ******* It seems clear to me that the design goal of the NAD 3140 was to be twice as good as the iconic 3020. It is rated at twice the RMS power (40 WPC), has two phono inputs, two source selection switches (listen and record), two Bass_EQ contours, two tape loops, two sets of speaker outputs, two led power meters, and even two power transformers that are wired in series to behave as one massive chunk of iron. All that combined with over twice the Main Capacitance provides a Dynamic Power IHF rating of 80 WPC at 8 ohms, 130 WPC at 4 ohms, and 160 WPC at 2 ohms. The 3140 is an all-discrete design. The sophisticated 7-transistor MM/MC Phono Preamp has both Phono_1 and Phono_2 input jacks DC coupled to an FET gate with no coupling capacitor. A very unique feature of the 3140 is its 5-transistor 12db BASS_EQ Amplifier stage that can be selected to extend the low frequency response of almost any speaker by an octave centered around 45 Hz (Tower Speakers) or 70 Hz (Bookshelf Speakers). While the additional demands on the power amplifier can be significant, this amp can deliver. Another unique feature is the S.L.C. or Speaker Lead Compensation feedback in the Power Amplifier. It is meant to compensate for long and/or light gauge speaker wire, but I find it pleasing under all conditions, and usually leave it on. NOTE: Unlike most power amplifiers, the 3140 connects to all Speakers as if in a bridged configuration. The Negative Speaker terminals are NOT common ground. They are actually the S.L.C. feedback for each channel.

A Good example of the NAD 3020A. 100% serviced and working perfectly. These amplifiers have remarkable sound quality and are suprisingly loud if you want them to be.. The A versions are often seen as having the best design in the 3020 series. This version includes Phono MM & MC inputs. The Original Motorola MJ2955/ 2N3055 power transistors still present. The front panel is overall good, but has a chink and small crack on the left side. Its still quite solid though - On the right there is some markings by the volume control too. Neither are too bad, but they are there to see. Check pictures. The casing is pretty good. Input RCA connectors are 24 Carat Gold plated as is the Phono earth connector. Amp has totally cleaned circuit board. L & R Outputs are equal at full volume. All potentiometers have been serviced (Volume, tone etc) and work with no crackles. ALL of the Electrolytic capacitors have been replaced including larger Power Supply Filter capacitors. It is imperative that these be replaced. Old capacitors of 40 years+ are well past their End Of Life. At best the old capacitors found in these amps today have values that are drifting and they will likely fail at some point. New multi-turn trimpots have been installed for Amp bias adjustment. DC offset and bias have been optimally set. Motorola Output transistors have been remounted on new Silicon thermal transfer pads, replacing old dried mica insulator/ thermal compound. If you would prefer 4mm Binding Posts for Banana plugs fitted in place of the Speaker wire grab terminals, I can do that for a small extra charge. Message me if you are interested in that. Great amplifier, stunning sound quality and guaranteed to impress !

Fantastic example of the much desired NAD Series 20 3020 Mk I. 100% working perfectly. This amplifier is the original mark I of the original 3020 series 20. It includes an MM Phono input. This one is in great condition, looks amazing and has an extremely clean front panel. Very few hard to see marks and blemishes. The top casing in good condition. The bottom is clean too. Input connectors are 24K Gold plated as is the Phono earth connector. The amplifier has been totally cleaned inside. These old amps need it - see last picture ! All potentiometers have been serviced (Volume, tone etc) and work with no crackles. ALL of the Electrolytic capacitors have been replaced including larger Power Supply Filter capacitors. It is imperative that these have all been replaced. Old capacitors of 40 years+ are well past their End Of Life.
