Deoxit switches and potentiometers. Resolder RCA, DIN, and Headphone jacks as needed to reseat and resecure them, along with any other questionable solder joints. Re Cap - Replace the Electrolytic Capacitors in the Power Supplies, Amplifier sections, and Tuner Audio sections. Ill upgrade the audio caps with nichicon, ELNA, Rubycon, and Panasonic audio grades while preferring 105C and/or higher voltage rated caps for the power supplies. I can also install any capacitors that you provide as desired. Note that replacing the power switch is an additional $35. If you hear a sizzling sound as you slowly push it on or off, then its time to replace it. International units at 220VAC are no problem. Please allow 7-10 days from receipt to return ship so that I have time to listen and confirm proper operation. The 30 day handling time is intended to include your ship time to me as well. Feel free to message me with any questions or to inquire about the repair and/or recap of other models.

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.

Whenever I manage to acquire an NAD 3220PE with all of the original transistors intact, I prefer to preserve and protect the Driver and Output Transistors by disabling the PE Supply, effectively re-configuring the unit as a 3020e. This 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 by Beefing_Up the RMS Performance with upgraded Main Caps, going up from 4700uf to 6800uf nichicon FW Gold. I have upgraded all of the other Electrolytic Capacitors as well. The Power Supply caps are nichicon, Rubycon, Chemicon, and Panasonic. The Phono Preamp audio coupling caps are nichicon MUSE Bipolar. The Control and Power Amp audio coupling caps are nichicon Fine Gold. It sounds delicious! 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 scratches on the top/side cover. Please see photos.
