Thanks John thats excellent help. I knew about the high Rp and the 7k trans. I figured that would lead to eventually a big triode amp. That has always been my goal except I felt I needed more experience to work with the high plate voltages. The speakers for this amp are very efficient so 2watts is adequate. I have to e-mail the amps designer and ask what he thinks of the 6.5k trans. They use I believe Hashimoto trans? How you doing with the Broskie pre-amp?
