This famous winding was connected a sealed and potted circuit with input from 2 EF86's and output to 2 ECC82's.
Nothing connected and only "F" , Rdc=15.9 ohm , L=811mH , Capacitance=33nF , Z=1k6 ohm . Same wire as primaries.
With 1kHz sine 1.9V to E (or D), I have 1.2V @ F , 57mV @ A , 68mV @ B and 94mV @ C
