Hi friends

I am a happy camper. 29 years ago, my OA20 got stolen, and it took me almost 3 decades to get it replaced (even upgraded, YES!)

Now, since I recently started to tinkle around with electronics, I thought why not build a SOAP myself?

Is this feasible? Has anyone done it already and could help with schematics/build-guides etc.? This would be so cool...

thanks already

I had one in th 80s. It was a simple but big PS that connected in parallel with the internal supply. There was a single trannie -around 350VA- followed by two bridges and then 22000uF for each channel. I think later versions might have had regulators as well, but making your own is perfectly doable
