Is it supposed to work?
Small class D amplifier driving an AB2 805 PP through a 1:12 transformer.
500V 50mA on each 805 (internal resistance about 13K), max g1 swing about 170Vpp for 35W output on 8K load, max Ig1 about 45mA per 805.
OPT: TTG-CFB8000PP - Tube output CFB transformer [8kOhm] Cathode Feedback Push-pull - Shop Toroidy.pl
I don't understand CFB, do you have an idea of how much the internal resistance of the tube will be reduced to? and what additional drive swing required?
