Hey all,
I have a Peavey Valveking 212 all valve combo that decided to give up the ghost on me a few months back, haven't had the time or moola to take it in to a tech yet but what happens is I switch it on, works fine for a few seconds and then loses sound (sort of like someone is turning the volume down until there's nothing). I've tried this a few times watching the power amp tubes at the back and they glow for a few seconds then suddenly go dimmer until they're completely dead (volume disappears with the glow, obviously). I've tried swapping them out one by one with a spare that I had lying around but no luck, so I'm assuming that it's not a bum valve that's causing the problem.
Initially, it would hold volume and "valve glow" for a few minutes before crapping out but over the course of a few days that time reduced to a few seconds so now by the time I've allowed the tubes to warm up and hit the standby switch, the thing is dead as a doornail. I haven't tried using it since December or so when the problem started becoming worse and worse. Any ideas??
