preamp pentode and triode that can hold 700-800V

(1/1)

ELS122:
I want to use EL34 tube's here and power it at 1.6Kv
but those other triodes and pentodes, I don't know any that can hold that amount of anode voltage.
also what tubes should I use here?

Gyro:
... about the same circuit.

Build a smaller amp to prove that your design works, say 400 - 600 V, then scale up in a couple of increments
