You need 200V caps for the output. You can probably get down to some value as low as 470uf each cap.
On the input you need 400V.

I have always used dead Switch Mode Power supplies for cap sourcing - they usually have a pair of 250V or 400V caps hidden away.

Another great tip Shoog - I found a MOT on EBAY - $13 each and a $1 light ballast. Better start thinking about the chassis

Shoog -- I would be very interested to see this - if possible would like to see the PS section as well including the pwer source for the 6as7 CCS. Now I am thinking to build a hifi of this first and then perhaps later a bass amp. thx.
