What is the I sub r of the plate at your operating point? What is the nominal primary impedance of your output transformer?
125 Henries is a (as the Donald would say "a huge load". At twenty hertz it's impedance is 15.7 kilo ohms. At 30 hertz it is 23.5 Kilo ohms. At one thousand hertz it is above 750,000 ohms.
