MCS Series 3865 or NEC AUA 8000 Integrated Amplifier. Needing Schematic ans service specs
I have a MCS Series 3865 amplifier with no audio out of the left channel. Upon a visual inspection inside the amp I found R405 broken at the circuit board, on what I believe is the speaker protection circuit board. It is the emitter resistor for TR 401. I'm going to replace the 470 ohm resistor and see what happens. I do not have a schematic or service manual. I am looking for these pieces of information. I'm wanting to restore this old amp. It worked flawless. My father purchased the complete MCS Series system in September of 1980. Includes the 3865 amp, 3710 tuner, 3563 cassette deck, and the 8265 speakers. he bought the 6720 turntable about a year later. This thing was BAD TO THE BONE when it was new. I'm wanting to bring it back to life. any help or input would be greatly appreciated. Thanks for reading!!
