Hi, Question for the group, please- I recently got a four socket bias meter. I installed the sockets and old tubes to check to see how matched they still were after many months of hard use. Surprisingly closely matched. The bias is set at 31mA which is 60% (485Vdc plate, EL34, -41.8Vdc grid). Since this is the first time having a meter watching the output tube current instead of me measuring things the regular way (1 ohm or shunt method) my hands were free to grab the guitar. This is where it gets interesting. Under a hard strum the current would jump up to 90mA (one tube) when strumming the current sits around 55mA. Stop playing and it returns to 31mA. I guess it makes sense that the tube is passing more current since there is an input signal/voltage to start producing more power.... but since this is the first time I've actually seen it I'd like to please confirm this with the group. When someone is doing an amplifier output power test what is the current of the tube when fully cranked?? Thanks for any information.
