813 SE triode amps - Pete Millett's DIY Audio pages
http://www.pmillett.com/813_se_triode_amps.htm
info on the 813 triode push-pull amps that he's built, as well as the triode mode curves for the 813. By the way, the grid lines on the curves are at 10V increments; the first (leftmost) is 0V, the next -10V, then -20V, -30V, etc. I operate the output …
An 813 Amplifier

This amplifier without modifications will allow to use the GM70and the 813(FU-13) output tubes. The 813 is a general-purpose transmitting beam power tube with thoriated-tungsten filament with a maximum plate dissipation of 125 watts. It is a very linear tube in triode connection with the same amplification factor

Does anyone know of a good tested schematic for a push pull 813 tube ultra linear design amp. I was thinking of 250 watts from two 813 tubes with ultra linear output transformer taps. Also, is there any reason not to use separate transformers for each needed voltage. The power supply will be...

813 beam power tetrode, the amplifier was unfinished and incomplete. There was also a power supply for the amplifier on a separate chassis, but the power supply had design problems, defective parts (particularly the filter capacitors), and was not operational. Since the amplifier would make a beautiful companion to the
