If nobody bellies up, contact Peavey, USA. -
the AH500 may be what you need.
I am not familiar with the amp, but the AH250, may be the AH500 with one power amp only
AH300 & AH500 attachedComment

Okay thanks! I haven't got a clue actually. Guess I have to open it up and see if it is a one power amp version of the 500.In this forum everyone is entitled to my opinion.Comment

Major suspects are transistors or fets. I don't have that much experience from SS amps.In this forum everyone is entitled to my opinion.Comment

If not remembering wrong, the 500 is 2x250 under a single hood, so 500 schematic should do.Originally posted by überfuzz View Post
And 350 should be the same as 250 with an extra pair power transistors.Juan Manuel FaheyComment

I called Peavey.
This is what they have.
Take note that on the power amp page, the box states it is for AH150 & AH250.
So you should be good to go.

I think I'll have a go at the power transistors, judging by the schematic they seem to run quite hot. Maybe they're just worn out..?
Eh.. Maybe I should open a new thread on this project in an appropriate section. I'll be back!In this forum everyone is entitled to my opinion.Comment

Generally if output transistors are running hot, it is due to a problem elsewhere, such as misadjusted bias.Education is what you're left with after you have forgotten what you have learned.Comment
