question about beefing up my monoblocks

[sorenj07]

They've got 282X power transformers (500V .2A), 193J chokes (10H .2A), a socket for vacuum rectification, 60W 6.6K UL output transformers, and two other octal sockets. Is a 60W KT88/6550 amp feasible? At the moment I've got KT77's in there, cathode biased at 380Va 64mA with 5R4GYB's in the rectifier spot..

One thing: My B+ reservoir cap is only 100uF, albeit a motor run cap so it should have good transient response or something?

I'd be willing to mount a little negative supply transformer on the bottom, some of which I could tap to feed a CCS in an LTP, if I wanted to try that. What do you think?
