Looks like someone previously attempted repair on this amp and did a shoddy job at it. Most of the transistors on the side are unscrewed and looks like a couple of them are even broken. Bah.

On further inspection, and a taste test, it looks like the spill that I was noticing on the board, is actually the capacitors leaking... I'm currently going over it with some isopropyl, seeing what I can clean off (its taken off quite a bit) I am wondering though, there's a connector for a fan... ha...

Good point, but I'm one of those "if it aint broke don't fix it" kind of people.

Or in this case "if it's not bound to break soon, only fix what will go out soon"



I may have to see about it though.

Awesome. I tried doing a search but I have a bad habbit about not typing the exact words I need to get legitimate and useful results.

I'll dig thru that forum asap, I'm really enjoying the poeple here on this forum too lol. Useful and informative, and quite nice as well.

no the big ones are the ones you need to worry about. I have an amp I am repairing now that a cap blew up on and they take part of the board with them when they go. Ah, so I should just probably replace all of them then? lol. The images from the link above made me under the impression that the larg...

Hey I really appreciate all the information. I haven't measured the zener diodes yet to see if they are still good or not.

I imagine I'll need to keep the same capacitance or is there a suggested replacement, and that's only for the front capacitors, not the larger blue ones?

Sure looks like someone dumped some solder on those diodes. Caps look original too. Yeah I really don't know any of the history behind this amp. Guy said it worked for a while in his truck but then it stopped and he got another amp. I'm gonna go back over a lot of the board and clean up what looks ...

32VAC it appears.

Ah, well I appreciate it! I have several resources though I should be able to find something. If I have any trouble getting them I'll give you a holler!

Awesome. 120V?

I'm not sure. Those Zener diodes, it appears to just be rosin.

I received this amp from a friend who said it didn't work. It looks like the main issue is that 2 fuses need to be replaced/installed. I've done a few searches and haven't been able to find a schematic. Here's a picture of it and the 2 fuses I need are on the far right side. They are the larger fuse...
