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.
