Harmon Kardon citation 2 bias question

@kellymack 

Remember the Marantz 8b bias thread?

Do you still have the Nobsound 8-Pin Dual Bias Current Probes Tester Meter? You can use it to check the bias.

Measure voltage across the 15 ohm cathode resistor, use Ohm’s law to calculate the current ( I = V / R ).

1V across 15 ohm cathode resistor = 0.067A

Plate dissipation = B+ voltage x current

Assuming B+ is 470V, 470 x 0.067 = 31.3Watt.

On the safe side, I suggest 1V (31.3Watt) to 1.1V (34.5Watt).
