I recently got this head and when I opened it up I found that the tube board is a little toasty in a couple spots. The guy who I bought it from said his friend played it with the volume all the way up and cooked it. I don't think I can repair it, would need a new board or two. What do you guys think? Oh, and sorry for posting so many image files!

Thx

Ouch!
I would be surprised if you can get a replacement board. You could have one made or seeing as there is not much on the board, you could just hard wire point to point components and wires.

One of the sockets was already moved due to an earlier burn out, so the point to point idea is probably best.

Point to point is what I had in mind as I do a lot of guitar rewiring and am really good with a soldering iron. I found a schematic, but need to learn how to read schematics before I can go that route. It would be great to get pics of the same board intact so I can visually see where everything needs to be connected....

Thx

I'm not familiar with that amp, but it looks like it is cathode driven by a solid state driver section, similar to a Musicman or some Peavey amps.

I'd start by checking all of the wires and connectors that are covered with soot. Remember that carbon is conductive and it should all be cleaned up really well before you turn it on again to test the transformers, etc.

Before you start rebuilding that point to point I would first confirm that the output transformer is good.
If you go to you tube there you can find video`s on how to test it with low ac voltage like from a wall wart type supply.

Thx guys. While I am comfortable working on guitar circuits (I have rewired upwards of 100 electric guitars and basses), I am not comfortable with working on an amp. So, I may just unload this thing. Anyone interested?

Thx

If you want to fix it, I might make some photos of mine (the same amp)but yours are melted down, I do not think this amp is worth working with anymore. Sad

If it is not too much trouble, I'd at least like to see what it should look like so I can decide if I want to try to solder point to point...

Thx
