I'll be straight up: my experience with tube amps over the years is very limited. That's why I'm asking this, hope it's not a stupid question. I just got a Peavey Classic 30 and it looks to be in good shape, seems to work just fine. Granted, I haven't been able to push it very loud, but its intention is to be a practice amp in my office for the most part. This is the first tube amp I've actually played which doesn't have the standby function. Whenever I shut the amp off, it pops fairly loudly. It's not something that sounds like the speaker is going to blow or anything, but I haven't had an amp before that does that. Is this a symptom of something that needs to be fixed? Or is it pretty normal for an amp like this? Also, I did see someone was able to modify their C30 with a 3-way switch for the power where it was "OFF-STANDBY-ON". Is that something I should consider for this amp which may prevent that or is that only so it can have a muted speaker but stay warmed up? THANKS!
