Hi there, I suspect an output tube in my Laney VC-15 has died as tonight it was working fine and then after a while went quite and the best way to describe it is to say i could only hear the preamp. I plugged my gt-8 into the effects loop (send and return) and then plugged headphones into the pedal which gives me a way of hear whats coming from the preamp and the sound in the headphones matches what was coming out of the speaker. The sound responded to gain variation on the drive channel and to the volume control of both channels but was soft enough to not bother anyone in the room next to mine when at normal levels the same setting would be pretty loud. So I assume maybe an output tube or both are dead...
My question is, is it ok to remove 1 of the 2 output tubes and play with only 1 of the output tubes in the amp for a few minutes just to troubleshoot the amp and see if 1 of the tubes is dead? (I dont have any spare tubes lying around to test with...)
I know this is ok with preamp tubes but I've heard you shouldn't remove output valves unless you're removing a pair like 2 out of 4, though I don't know if this was just meant as a kind of dont leave your amp with 1 out of 2 output valves on a permanent basis like you can when u remove 2 of 4 output valves to lower the power.
Any help would be appreciated, thanks ?
