Did any person on the forum attempt to use 813 beam power tubes in an audio amplifier. Or was such a vintage valve amplifier ever made.
For 2 valves in push-pull Class AB1
The min Va is 1500 for 260 watts output
The max Va is 2500 for 490 watts output
Data: RCA Transmitting Tubes Data book
This is using really lethal voltages.
Kind Regards
Charles
