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.

Perfect phono preamp. I no longer have a need for it! I’ll ship it to the lower 48 for 15 dollars. Power supply is in included. What’s in the pictures is what you get… please use the pics for a detail inspection of the item. No scratches or dents. It is a little dusty in the pictures. But it will be clean when it arrives. Good luck.

This was part of NADs Power Envelope series, which was an all-discrete class AB rail-switching design that allowed momentary peaks to exceed the amps steady-state available power. This power amp is rated at 40W per channel continuous @ 0.03% THD. Its clipping power is closer to 60W per channel. Its a lot of amp in an understated package. This amp has been freshly re-capped and restored -- *all* electrolytic caps have been replaced, with premium parts in signal positions and low-impedance parts in supply positions. The old single-turn trimmers, which were a common failure point, have been replaced with sealed multi-turn trimmers, which allow both greater reliability and more adjustment precision. The amp was just realigned and biased and is ready to play some music from your favorite preamp. All the transistors are the original matched parts. RCA inputs, binding post/banana plug speaker outputs. Ill also include a copy of the service manual (extremely hard to find) in case you ever need to have it serviced. There are a couple scratches on the top of the case.

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.
