Thanks for posting this. A very specialized case.
The output stage works in pure class B2. 811 tubes (not very linear, to put it mildly) are biased at about zero volt. Although cathode follower has low output impedance, 6W6 triode connected, at 25 mA cathode current, will have difficult time delivering the calculated 42 mA peak grid driving signal current and 1.5 W driving power required for full output power of this amp. Tons of power, but a lot of distortion. Probably was intended as PA amplifier for sporting events, like Daytona 500 races.
