Solidstate Amp Repair Question(s)
Posted on 4/1/24 at 7:00 am

Anyone have experience repairing solidstate amps?
I've ordered a main PCB for my Ampeg SVT-7 Pro thinking that it would be an quick swap out. Multiple reviews online say it's an easy 15 minute job, but is there anything I should consider or keep in mind?
Or is it really just as easy as unplugging the old one and installing in the new one?

I remember reading that the SVT-7 had issues. Was it a chip issue?
I’m not an Ampeg guy so I don’t have a lot of experience with their amps.

Yep - it's an auxiliary power supply controller chip that overheats and causes shutdown/power cycle issues. Ampeg had to go through at least 7 board revisions before fixing the issue.
It's a $10 fix if I want to buy the chip and solder it on, but my soldering skills are basic at best.
Figured it would be easier to just swap the board.

Gotcha. I’m not good with the iron either.
Maybe see if Ampeg has a local person to you that they farm out repair work to and call and ask them.

I haven’t repaired an amp but I’ve repaired the amp PCB in my electric pianos (Wurlitzer mostly), you’ll still have to solder the cable between the PCB and the speaker. If I can do it anyone can.
You’re probably doing the right thing with the chip though vs just getting a new board. When I see a chip I don’t want to go anywhere near it.
I would say if you solder it on and it still doesn’t work, bring it to an amp guy. If you’re in Louisiana it will probably cost you $100 if you have all the supplies.

From the pictures, there's just the one ribbon cable. Go for it. I wouldn't heat a board with that much epoxy unless I had to.
