Simple SS Power Amp Build - +/- 40V Push/Pull
« on: December 04, 2018, 03:25:24 PM »
hey guys!

been a minute -

trying to clean out the crap pile while things are a bit slow at work -

i have this Polytone amp thats been taken apart for quite a bit now - the preamp is perfectly fine but somebody tried to "repair" the power amp and its just a total disaster.

the PT is fine and I decided I am just going to gut it and build a simple power amp from scratch so I can get this thing back to life -

I've got +/- 40V and heatsinks for two output transistors -

Also have a second, lower voltage tap (about +/- 20V) -

can you guys recommend a simple power amp build I can retrofit to this thing? its got a nice cab and a nice preamp with reverb and tremolo and everything - shame for it to die on this bench!

There are a bevy of class d amps available on the net.

Small & simple.

Pick one that utilizes the +40/ -40 Vdc supply that you have.
