Get the cathode voltages for all the 6sn7 cathodes.

Using ohms law you can then calculate the total current draw from the B+ supply assuming there isn't any shunt current (like a bleeder resistor or voltage regulator, etc.)

Yeah, If you know the B+ at the output of the filter and the total current draw you can get a power transformer that will make the thing work as designed.

If there is a voltage drop resistor in the power supply that carries all the current you could have him give the voltage measurements on either side of that.

I wish you had a schematic. I can't find one on line.
