Marantz 4025 Receiver Deluxe Upgrade Kit Genuine Parts Restoration
Our kits use only the highest quality parts from authorized distributors. These kits save you valuable time and headache in sourcing the parts yourself. Deluxe kits, unlike our ultimate kits, do not include tuner parts. 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. ________________________________More Details____________________________ Quality PartsAll signal path caps 4.7uf or lower are replaced by sonically superior film caps, most by WimaAll transistors are made by OnSemiElectrolytic caps are primarily Nichicon.
