I replaced my HJS tubes with EL34's and simply adjusted to about 70mV. Now I have a set of KT77's I want to install, how do I check for plate voltage so I can do the calculation?
a pretty safe method would be to touch off the black lead on the chassis and the red lead on either the brown, red or white wire spade connectors at the output transformer secondary terminal, as these are insulated
