Apologies if the answer to this query is on another thread but can't seem to find it. Can anybody tell me the bias current or current through the output valves & how to work it out. Ta.

Hi

Measure voltage at each pin 3 to ground (put a probe either side of each 270R cathode resistor R24,25,26,27 if it is easier to get at). Should be 11v. Ohms Law 11/270 gives 40mA current.

Thanks for the quick reply Richard. Measures fine. Easier than I thought.
