I've heard you should take a crappy screwdriver, ground one part of the shaft and then touch the capacitor with the head. Something like that.

  I have a (crappy) screwdriver with some bite marks on it from doing that to come 1000V caps in an old panasonic stereo amp. It can work. It's not a good idea, IMO. What I believe is safe enough for me to do... but not so safe that I'd recommend anyone else do it... is to measure the voltage between the high voltage supply and the ground in the amp, and see what you'll be getting if you touch it. If it is more than a volt or so, then connect a 10K resistor between the HV and the ground. That said, if you don't understand why you should do that (or why taking life and death electronics advice from strangers in a comment thread is a bad idea), then you might want to just not get around in there, because you can lose fingers or even die if you don't know what you're doing. :D Go circuit bend a speak and spell or something, and leave tube amps to folks who want to know more whys before touching stuff. :D
