| one mod you can do is a couple of 1 ohm 5 watt resistors and put them between ground and cathode or cathode resistors (depending on output amp tube) and permanently mount some panel meters on your chassis. then another between cathodes.
alot of people forget to look at differential current. this is caused by either the phase splitter tube getting weak, or associated circuit, or the bias feed grid resistors drifting out of tolerance from each other ( bias voltage screening resistors after voltage adjust trim pot like in JCM800's)
