It's not hard.

Turn off amp.
Let caps drain (no clue how long it would take).
Pull out old tubes.
Install new tubes.

The tubes are in sockets, so you can just pull them out and pop some new ones in.

be sure to put them in the correct order though. I don't remember what that is... =\

If you have to ask, don't do it!

Tube amps have lethal voltages if you do something wrong.

It won't cost too much to have someone do it properly either.

Capacitors inside the amp. They have a 'bleeder' wired to them that after a certain amound of time (not sure how long) will drain the current out of the caps. This makes it safe to wokr inside the amp.

so I guess that after 1 days leaving the amp unplugged it will be safe to handle it? id use gloves anyway :S

If it has bleeder resistors in it (they slowly pull the charge out of the caps and to ground) [and it does], yeah, probably.

Tubes are mounted on top of the chassis inside the cabinet. You won't be poking around its guts. Just turn the amp off, wait awhile, take the cabinet off, pull out the old tubes, and put in the new ones.

BAM. Done.

Think about it:

If something as routine as changing tubes was deadly, don't you think the manufacturer would keep in mind that most users will try to replace their own tubes to save money on tech fees and therefore HAVE to make it safe to do, or else they'd get their asses sued off?

Heck.. you don't even need to turn the amp off to replace the preamp tubes. You could swap 'em out on the fly. Wouldn't recommend it though, who knows what would happen.
