Hey folks new to this froum looking for somw help... i have a VH4 two tube fault lights have shown up... tubes still appear to be glowing as normal?? How do I know if it is a fuse issue??? Or a tube issue?? And if i replace tube will I have to bias?? Or can u replace tube and not worry about biasing??
 
not an expert but i would try changing to all new tubes first, set bias and change new fuse... if it still blow maybe other technical issues? do call Peter Diezel he is always on standby 24/7 here

It would be wise to change power tubes, bias and while biasing checking that everything is in order with your closes amp tech!
