Here is an even more obscure formula for determining power transformer secondary currents: you take the open circuit voltage (1/2 secondary), and divide by the DC resistance (1/2 secondary)and multiply by 25 for a capacitor input filter. Seeing as the amplifier had a solid state PI and OP section, my guess is that the current available would be relatively low, with a B+ somewhere under 300VDC. Any other parameter can be determined by simply hooking up a test circuit. Good Luck.
