Question about Nakamichi Audio & Video Receivers
I am a electronics engineer and I have Nakamichi 680ZX cassette deck, its FL indicators are not functioning.
I had checked for both channels output signals on switch PCB. I had received audio signal on pin # 5 of IC 904 (RC4560D) on Indicator PCB C ***'y, further no signal on pin # 7 but (-)10 Volts DC with respect to ground, of the same IC.
I would appreciate if you could guide me to rectify the problem. Please also note that I have complete full service manual for Nakamichi 680ZX.
