With 400V on plates, biased to 86mA per tube, this amp produces about 35W of very nice audio before clipping. Actually I biased the output tubes for about 92mA each, using 470 Ohm cathode resistors, with no problems. Input stage is a triode-connected EF86 directly coupled to a 6N1P long tail phase splitter. RP1 must be adjusted for minimum distortion. In my amp I used fixed 18k and 22k resistors for R6 and R7.
Power supply is heretically conventional.
I do not use chokes in Push Pull amplifiers and since I'm absolutely out of SE field - I never use chokes. A simple voltage divider can be used for this purpose. Perfectionists can try an RC network connected in parallel with the EF86's anode load resistor. Even without this network, amplifier has no signs of instability. All resistors in the prototypes are Philips metal film.
