Hello and welcome!

First off what is the issue your having with that item of gear?

Is this a mixer?

It's a kasino lounge guitar amp. It's the pc5131rev-o board. It's fried. I replaced the 1n2069 200 v zener diodes already, replaces the two transistors, and I've replaced the 5349 diodes too. But now it's humming really loudly for a few seconds, then blows the fuse. When I first got it you could see where them white zener diodes had got super hot but it worked for a short time. Now after replacing all That. It hums really loud like I said before and then it blows the fuse. I think the pc5131rev-O is the power board for the entire amp. None of the effects work either. I have no idea how to post a picture on here of it or I would do so. PleAse help

I've replaced both transistors, the two 5349 diodes and the four 1n2069 diodes. Now when I turn it on it hums really loudly and blows the fuse. Making me think that it's the poly and ceramic capacitors. But it doesn't list what they are on the schematic and I have no way of testing them so I was just going to order new ones.

We can not post pictures here.

None of the capacitors that you are asking about would make for your blowing fuse issue.

Please send me a photo of your schematic and take it in two sections, also send me some good shots of the whole inside of the amp and the board your working on.
