Marantz 2220B Receiver Ultimate Upgrade Kit Genuine Parts Restoration
Our Ultimate Kit for Marantz Receivers includes everything you need to electronically restore and upgrade your Marantz. This kit includes: 59 Capacitors36 Transistors & Diodes 5 Bourns Trimming Resistors The included filter caps are upgraded in capacitance (from 6,800uf to 10,000uf) and voltage (35v to 50v) which will result in better bass and dynamics. The 2220B used two different relays over it's lifespan, they are not interchangeable. This kit does not include the relay (and is priced as such) but if you open your unit up and let us know what relay you have, we stock both and will include it for an additional $16.00 if so desired. You can easily ascertain which relay you unit uses. The more common relay has a clear cover while the rare relay has a milky looking cover. If you would like the clear topped relay, we have it available here: https://www.ebay.com/itm/314784802800 Our kits use only the highest quality parts from authorized distributors. These kits save you valuable time and headache in sourcing the parts yourself. Having serviced and restored virtually every Marantz receiver in the past, our kits are accurate and vetted. If you can solder and desolder, consider yourself handy in any other way, and are deliberate and thoughtful, you can do this! Any audio gear over 20 years old can benefit from this procedure. Any unit over 30 years old risks failure of other parts without it. Electrolytic Caps drift and fail with time leading to a less detail, transient response, weak bass and mushy overall sound as well as potential failure leading to costly repair. The sonic difference will likely astound you. Customers consistently tell us how much better their unit sounds after a restoration using our kit. A restored unit also greatly increases its value. We can provide more details on this unit if you’d like. Our documentation isn’t top secret. Parts are separated logically by board.
