I run my 32V3 at 700 volts and 200 ma for 100 watts out, and I have KT90 hifi tubes as modulators.
Been running that way for 30 years without a single crapout.
I solid stated all the rectifiers and the transformers run at room temps.
I also use it as an exciter so it spends a lot of time turned on.
Mine is not a collectors item, its missing a cabinet and a driver transformer, so I do not worry about its resale value.
And 100 watts is good power on 40 meters.

The 32V-2 is what I use most of the time on the AM nets with very good reports.
Thank You, Collin
