Roland JC77 dead right channel

[mlrpa]

Hey peoples, I live in an area of the world, NJ, that amp repair is something never uttered. So a qualified tech, well, doesn't exist. (I have left many messages to the supposed experts in the area, and got no replies. And please GC? Are you kidding?)
So... I have a Roland JC77, a stereo amp, and the right cannel is mostly dead. The smallest amount of volume, thru the speaker, and thru the line out. My reading of schematics is, ummm, well, almost non-existent. I would need an idiot diagram, showing where it's located on the board, and what to remove/replace. So, is there anyone that can help???

mlr,

Give me a few moments, I'm under a deadline just now.  Might be a few more moments beyond that, but I'll get back to you as ASAP as possible.

OK, laughing boy.....


I'm reminded that you posted this same amp, with almost the exact same symptoms, clear back in 2007:

I'll ask you to go through those non-schematic, non-test equipment procedures again, swapping left for right as needed. Note that the last post also contains a good hint as to what could go wrong, so check those things too, then report back here for further insructions on where to go and what to do.
