I have to measure it with the amp boards in, anyhow I have 50V across each cap.

It has 2 separate transformers.

Yes, 70Vac CT = 35-0-35Vac and will give ~+-50Vdc PSU.
This is perfect for a 100W into 8r0 amplifier.

These transformers may just about get you 180W into 4r0.

Actually I was wondering what AndrewT would say.

I was looking at this guys amp with a regulated 35v from ~50v. Roman Black's gainclone amp
I could maybe do something like that, even a bi-amp setup if the space allows.

What would you do with them?
