Marantz Cassette Deck Repairs
Marantz SD-6000 Stereo Cassette Deck
This would not do very much, the deck stopped after 5 seconds the right hand playback was non existent except for some hum. The Dolby IC was to blame for the non-playback, I replaced the LM1011. The optocoupler was refusing to opto couple, replaced the LED with a white LED.
