I am experiencing issues with my Marantz DD-82. At the beginning, the device was able to read the TOC of a DCC, but no audio at all. It had issues too when playing analogue tapes, the sound was very quiet and unclear. So I decided to replace the old SMD caps on the read write board and on the digital board. After I replaced the caps it is not recognizing the TOC of DCCs at all and analogue playback is nearly impossible and noisy. It sounds like when you tune your FM radio to a frequency that is not occupied by any station.
No analog could mean a problem around pin 16-18 I believe. The last pins of the flat connector on the Read-Write board are the Analog Signal. There is a capacitor of 68uF on top of them. That is most likely the problem. Either the side a-b connection on the board, a bad connection on a trace. Hopefully not the head.
As you see in the video I have a loud rustle noise when playing analogue tapes. When I am using headphones I hear the music on the tape but very quiet and you can’t separate it properly from the noise.
I replaced the caps on the read write board first. As the situation has not changed I replaced the caps on the audio board too (I think we mean the same one, it’s the smaller one of the two socketed cards).
