OK, long story as short as I can make it: Bought a Peavey Royal Valve 8 about a year ago. Cheap 5W tube amp. Fiddled with it, actually did a pretty big room gig with it, sounded only OK but I figured I'd mod it later. Then this: 1) Microphonic tube stuff. I replaced pre-amp/power tubes, was the power tube. This lasted about a week then: 2) Started crackling/buzzing/fuzzing intermittently, then constant, any volume, any guitar, both channels, any setting. Bought new = full warranty so took back to dealer. They had it for about a month. 3) Got it back--couldn't reach 'repair guy' to find out what they did--took it home & plugged in = zero sound, no hum, no buzz, nothing. Checked speaker leads etc, tubes, channels, etc etc, tubes glowed, whatever, back to dealer. 4) Another month or so, get it back. Plug in, immediate & loud 'buzz/distortion' on any bass note below about 2nd E at any volume, including sleep level (like 2). Back to dealer and this time I talk to 'repair' guy, play it for him. He asks if I've been playing at full volume with gain pedals, answer "nope" and explain it was completely dead. He says he replaced speaker the first time around cuz it was 'blown' and I must be playing it too loud. Explained that was hardly the case... 5) I leave town, call two months later. Repair guy says he talked to his dad, a PV repair guy, and that this amp was designed for bedroom playing and this is nearly a quote: "Like you get up in the morning in your bedroom and turn it on and play a few notes at low volume, that's all it can do. It's not designed for much more than that with one power tube + an 8" speaker". I tell him I've owned tube amps for about 35 years and still have one or two I bought at least 25 years ago and they sure don't do that" and "are you saying I'll blow the speaker if I turn it up" and he says "Yeah, they just can't play except for really quietly" so I say I'll pick it up and go from there. My goodness. It's got a short on the PCB somewhere but time to take it to a service center. Tempted to just pull it apart and learn but it's under warranty...I do wish I coulda helped him understand the thing a bit more because he believes what he told me. At least I've finally got the perfect 'bedroom amp'.
