I heard that these things even unplugged could kill you if you're not careful. When replacing tubes, to be absolutely safe, how long should you leave the tube amp unplugged before its safe to work inside?

There's a way to drain the large capacitors that are holding the charge. You'll have to find that, I'm sorry, but I can't remember. If you wait for them to lose their charge you'll be waiting several months.

that sucks. I don't want to call in a tech just to replace tubes. I work inside computers all the time, but a computer can't kill you if you touch the wrong part.

To drain capacitors, find a model online of the inside of your amp, find the capacitor, then search this forum. I know its been asked before!

If you're just replacing tubes, all you need to do is unplug the amp and let the tubes cool down.

If you're going to be playing around with capacitors you should manually discharge them with some tool, I don't know what it is.

fair enough. I just like to be extra cautious. I haven't had my amp for a year yet but I plan on replacing tubes on the year mark.

whats the suggested intervals for tube replacements?

power: every year?
pre-amp: ??

I'd have a spare set of tubes on hand, and just replace them when the amp seems to be off, more noisy/hissy than normal, or your volume isn't as loud as it should be.

Generally speaking, poweramp tubes usually go every year and preamps every three years. No need to replace them until they start to crap out though

i haven't replaced anything yet. I like those numbers alot better.

some site scared me though saying that if your power's go up, it'll break other parts of the amp with it.

I rarely crank up my amp past 3 or 4 though (2 usually), or turn the distortion channel much past that nice bluesy-rock tone of 3-6 on pre amp. The classic 30's heavy distortion isn't my cup of tea and I have a smash box pedal for that. I love its clean channel and its warm OD channel when turned mid to low.

Plus my acoustic-electric sounds GREAT when I run it though this amp.
