I have had 4 470 uf 400V KMN capacitors each amp in two 'once were' LEAK St20s

Since the late 1990s there were three of them in the amp wired in triode mode, and four for the pentode mode amp.
Both amps are now in pentode mode and one of them has had a 4th cap added, in the last year or so. My techie may have checked and replaced one or two of the original 7, but I can't recall that on any of his reports and bills.
The last two in the PSUs are bypassed. On each amp one of the caps sits in the hole where the GZ34 rectifier was. ;-) and :-)
4 over rated Soft Recovery SS diodes in a full wave bridge and snubbed to boot!
