Mind my dumb question, once I measure them can I bring them up to 30ma or is that too hot?
It’s been a while but from what I remember, the chart or bias range for each pair of tubes is on the back upper chassis near the test points. Any multimeter will do, Amazon has a ton of them. The bias chart or range refers to 2 tubes total milliamps if I remember right. So, for EL34s I’m guessing the range is 60-80ma for both tubes…then the same range for the second pair if all EL34 for instance. If running KT88s then it jumps up I think to 70-90. Just guessing but pull off your back panel to get the real numbers.
