Hey guys,
I've been building some effects pedals, but now I feel like moving to the next level, which is repairing/building amps. Fortunately, I just got a simple SS amp from a friend to work on (Matrix ma30c)
and I have a few questions:
1. I get radio frequencies and a lot of humming when I connect my guitars to it. Pretty sure it's a grounding issue. I believe I need to replace the power cord to a standard european power cord with a 3d grounding pin. What do you think?
2. I know that SS amps are safer to work on and that the filter caps drain faster. What's the best way to drain them? (safety question)
3. I took a photo of the filter caps and there is some glueish stuff hanging from one of them. It doesn't seem like a leakage from a cap. again what do you think.
4. I don't have a good access to the soldered part of the board. therefore I cannot reach the leads of the caps in order to drain them. Do u have an idea how to do that without disassembling all of the pots and jacks?
Thank you for your kind help.
