In Reply to: Cathode Bias PP tail questions? posted by danlaudionut on April 27, 2005 at 10:55:29:
Boy that's not going to be a cheap amp to build. B+ up around the 1KV area. Driver is going to need to swing a lot of voltage plus the miller cap. No small task. Anyhow I'd vote for fixed bias. With a healthy negative rail I'd imagine you could direct couple to cathode followers to drive them. Cathode bias would cost you quite a lot of voltage...I mean bias point is like 150 volts or more assuming B+ in the 1KV range.Sorry, I know I didn't address your basic questions.
