Early on in the power supply. If you have a CLC or CRC filter as the first section, measure the voltage drop between the two capacitors. Take the voltage and divide it by the resistance of the resistor or the choke DCR. You can monitor this as you ramp up the voltage. When you get to 100mA, stop increasing the voltage and start measuring the various voltage drops in the amp, Plate resistors, cathode resistors, B+ dropping resistors. You will find a voltage drop measurement that is higher than the others or higher than it should be.
