To anyone that works on amps (Peavey Windsor)HELP!

[endofall]

Hey guys I own a peavey windsor. The other day I turned on the amp and it made a static sound then blew the fuse. I noticed smoke coming out of the chassis so I opened it. I haven't owned this amp long and it looks like something was spilled on the power amp pcb board, so I cleaned it off to the best of my ability, hooked it back up today, doubled checked my work, plugged it back up only putting tubes in the 2 outside sockets. When I turned the amp on it made the same noise and then there was a flash in the socket from the PI. So I opened the amp back up, and took some pictures, both power amp sockets for the 1st and second power amp has burn marks around some of the base, also D12 has blown. Any advise on what could be going on would be great!

Generally when a tube socket arcs like that you want to go ahead and take it out and replace it. make sure you remove all that carbon because it will cause arcing again. I've had this happen on a JCM2000 before. This could have just been a tube failure, but it might be an amp problem. The easiest way to get tube sockets out is to just cut the socket off the legs and then take each leg out of the pcb individually.

Looks like the sockets pictured are for V5 & V7
I'm guessing it was caused by tube failure. Hard to diagnose through internet though.


Also, this should be in EQUIPMENT, but i don't have the POWER to move threads. AAAAAAAGGGGH

Hey thanks for the reply. It is V7 and V5, also I posted this in equipment as well. If you want to can just pick up on it from that point. Do you have any tips on removing the tube socket? Thanks

Just do what normal people do -- beat the hell out of it until it works again.

thats what I would like to do with it!

Had a very similar problem, with a mesa recto i owned about 5 years ago.

It was a blown screen grid resistor whatever that means, and it fried the tube socket pins like in your pic.

Take it to a qualified amp technician, it is repairable and the fix may be under warranty. Took the guy 10 min to fix it, shouldn't be a big deal

good luck!

Thanks for the replies guys, I have removed V5 and V7 and cleaned up the board, I am going to continue to replace everything around these sockets as well. I noticed while cleaning the board that about two traces have lifted when I tried out the amp last time so now I have that to deal with. I talked to the local tech in my town today, he advise that I start with replacing the tubes and sockets. Any advise on what to do about the traces

It looks like a single layer board. Cut the trace and wire point to point if the trace is suspect.

Did the actual solder pads where a component would attach lift, or was it actually a trace in between components?
I remember the pads wanted to lift when I was messing with the windsor i used to have.

You can always bypass traces by soldering components directly together or any other point they need to connect to.

Sorry I used some bad terminology. It was actually the pads that lifted and they have only lifted slightly. Should I just continue to work around this with some extra TLC?

yeah, that should be fine.
