Sweetbeats, Yes, I followed your instructions before, disconnecting everything from the unit except for the send (or monitor, or whatever i was testing) to my monitors. They did reflow a number of bad joints apparently. They said they never heard the problem, but did see, on internal...

Well, I finally heard back from the tech. He never heard the problem I was having, which seems crazy, but that's the frustrating reality of intermittent issues, I suppose. Upon visual inspecting inside the unit, he DID find bad solder joints on the buss pcb that connects all the mixer/channel...

Thanks for the advice, Trance. It's at the shop, now, so hopefully I'll get some good news soon.

cool. Thanks man.

Thanks, Sweetbeats. Hopefully this helps whatever tech I find. If I understand your explanation right, any unrectified AC might explain the 60hz sound at the tape outs, yes?

Yeah, man, if you can point me to those threads I'd appreciate it. I'll search some in the meantime. I did test again briefly and the noise is at the bus outs as well. The tape outs are still making the nasty 60hz sound. Is the concern that the power supply could hurt something else in the...

Hmm, the extender cables are probably over my head--are they easily explained? I'm happy to take it to a tech, but I'm out in the country, so it probably won't be easy to find someone. Would it be worth me trying to recap the power supply card and hope that does it, or is that a foolish...

Sweetbeats, THANKS for the pic of the signal chart. Now I see that page in the manual. A new development: All play/rec cards and DBX cards are still out. The problem is still occurring at the channel sends, and at the stereo outs. I checked the monitor outs and headphone outs, and those...

Maybe I'm missing it, but I don't see the signal path to the channel send on the pictogram signal chart. Can anyone explain the path, particularly in RMX mode?

THat is correct. Thanks a ton, Sweetbeats!

The other day when I took out all the cards I heard no problems, but I was thinking this could have been just the intermittent thing not occurring. So, I just did the following: removed both DBX cards--still had noise removed each record/play card, powering up each time to check. The noise...

Ok, Sweetbeats, the problem is back today. (I was listening to some tape and I heard it through the monitor outs, though it wasn't printed to the tape). I disconnected everything and listened to a few of the channel sends, and sure enough the crackling was there. I did not at any point hear...

OK, for now I'll wait until the problem returns. I reseated the cards to the right, and noticed a heat-damaged area on the Reel Servo PCB. ANyway, this could be totally unrelated, but I thought I'd post pics. Something I should replace? What is that part? Thanks.

Sweetbeats, NO, there's no noise at the tape outs. BUT, today I have yet to hear noise at the sends either! This actually seems more frustrating then good. I guess, in terms of chasing this intermittent problem, the tape outs are clean for now, but it could just be that the problem isn't...

It did not occur at all with the amp cards removed, but the DBX cards were removed as well. Perhaps I should have tried it with DBX cards in and all amp cards out?
