I just bought my first tube amp! Very excited. Now I'm trying to learn everything I can about it. I can't seem to fully identify the tube order. I've pieced together information from a few different sources and labeled what I found out on this picture. Can anyone confirm I have tubes V1 through V5 correct? I was told the 7025 on V4 has to be balanced. But did I get the correct slot labeled? What is the order of the power tubes? Since we're on the question of tubes I've read that it's possible to lower the watts by running with fewer power tubes plugged in. They need to remain in as pairs. Which pairs? ie it should be possible to run with 2,4, or 6 tubes at a time.
