Yamaha M-4 Stereo Power Amp in excellent condition. I just finished a complete restoration.All electrolytic capacitors replaced, mostly with Elna Silmic II. The two large power supply capacitors were replaced with Nichicon FG High Grade Audio capacitors ($42 each). The output relays were also replaced. All internal adjustments were made per the service manual. The amplifier was then run in dynamically for 100 hours. Measurements were then taken again and fine tuned. In DC mode, the audio circuit sees no coupling capacitors. This amplifier holds it's own and sometimes betters many modern audiophile designs, especially now that it's been rebuilt with modern, high quality components. Includes owners manual. Price is firm, no trades, buyer pays shipping, PayPal adds 3%. Thank you.
