Glad to have found such a nice group and thanks in advance!!!
The Marantz DD-82 I have is exhibiting occasional and somewhat sporadic drop outs on material recorded onto a DCC. Playback of other material previously recorded on a recordable DCC sounds fine. Analog cassette playback is fine. Just when I try to record on a DCC I get drop outs. It is worse on side A than side B. I have inspected the tape under magnification in areas where drop outs occur and do not see any anomalies on the tape. I have cleaned the head with IPA as well as the pinch roller (also used some rejuvenator on the rollers). The side A roller does have some inward dimples on it and from reading your forum I understand bad rollers can contribute to drop outs.
When I received the deck, the transport operated fine but there was no output from the deck and nothing on the meters in both analog or digital formats. I changed the SMD capacitors on both the Read/Write and Digital Audio boards. Many were bad and there was some leakage. I cleaned all the areas with nail polish remover and or IPA. Checked the cap pad traces for continuity and checked the A/B through holes around those caps for continuity. They all tested good. Hope I got them all.
Still no audio but a check of the power supply revealed a bad 1 ohm fuse resistor. Replacing this brought the audio back, but revealed the drop outs on recording.
Entering into the service mode (and I admit that I’m not sure what I’m looking at) I noticed:
Most of the modes show 000 error rate. Main 6Ch showed 100. Not sure if that is bad.
Also, “Display All Error Rate Ave”. was 000000F0 and “Display all Error Rate Real Time” was 00000010. I don’t think the F is a good thing but not sure. Could this be causing the drop outs? Do I need to recheck the Read/Write and Digital Audio boards?
Thanks again in advance for your assistance.
