Ampeg micro-VR head repair

Did you first put a patch cable in the effects send & return jacks to see if the output comes back.
I had to clean mine a couple times when I had one.

I wouldn't try to fix it myself, I know I don't have the knowledge nor equipment I'd need to do it. But I wouldn't asume that OP's "undisclosed amount of electrical knowledge" is insufficient based on how he writes on a forum. I assume he is an adult that can judge his own skills; I mean, he is asking for the schematics before opening it and sticking his fingers inside, that's enough for me to "let him" try it if he feels confident he can handle it.

I disagree that writing skills automatically equate to electronics knowledge and experience. I wouldn't let Ernest Hemingway work on my amp unless I also knew he was skilled at electronics. I also don't believe in encouraging others to take on potentially dangerous tasks without knowing their qualifications.
Now if you wish to make valid, relative arguments in favor of your point of view, I'll be glad to debate you. I, however am not interested in trying to have a logical discussion against non sequitur comparisons.
Show me the OP's qualifications, and if they match up with the task at hand, I'll gladly concede the argument.
Thank you.

It's a bass amp, not a nuclear reactor. Anyone with some technical knowledge in electronics and some adequate tools should be able to repair it. It might be more cost effective to get a new board, but you don't loose anything by opening it up and taking a look at it first.

Clearly you are not familiar with said electronics or you wouldn’t have posted what you did.

This is a complex power supply and amp made to be replaced at the board level.

I do have the chops to repair something like this (I have designed a few my career), but it would cost more to repair than replace in general.
