With standby off (i.e all systems go) on my 6505 I have almost no output and a four 6L6's glowing blue in the back of my amp. There is volume with the master right down and not much more absolutely cranked.
Safe to say power tube problem; do I need two new sets of 6L6's (ouch!) or can I narrow it down? I need this up and running for Saturday.
EDIT: nevermind, apparently glowing blue is alright.
Can you run a 6505 on two power tubes? Some amps will run that way on half power... it might help isolate any power tube problems you might have.
I'd just take it to a tech really unless you can quickly and cheaply try out a new set of (tested) power tubes. Do you have any old ones lying around?
