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.

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. 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 installed for Amp idle bias adjustment. DC offset and bias have been correctly set. Output transistors remounted on new Silicon thermal transfer pads, replacing old dried mica insulator/ thermal compound. All Solder joints have been checked. This amplifier has a really truly stunning sound quality guaranteed to impress. It is no surprise this is the most desirable version of the 3020 ! Delivery will be with Royal mail Special Delivery by 1pm next day Collection is also welcome from North London N15 Sorry No International postage
