First time Biasing tubes


When I'm checking the bias and adjusting the bias -- what is it that I don't want to touch -- my VTL manual talks about all of the high voltage lurking in the amp -- which suggests there are things I don't want the probe (or my hand) to make contact with -- but as a newcomer to tubes, I really am not sure what I'm trying to avoid doing in the process. Thanks in advance for your help.

Rather than write a new thread, I thought I would just add to this one since I am a complete newby to anything electronic and need to set the bias on a Scott 222-D integrated amp. I will drop any pretense of pride right here - I honestly do not know what I am doing!

I have a volt meter and know where to touch the leads (though not sure which one I should touch to red or black). I see a bias pot, but there are other pots near it labeled "balance," and one very close to the bias pot. Could this be a second bias pot? Ugh. I mean it, I need real baby steps here - even what to set my volt meter too and which scale to read from. Thanks in advance!
Thanks Marakanetz!!! - I think I get it now! There are two bias slots marked left and right and now that I think about it, the two pots I see may be actually be two bias pots - one for right and one for left. Does that sound right/possible? I was applying my voltmeter to both bias slots (duh!).
Marakanetz - I actually understood you the first time, but did not make that clear. Two bias slots - connect red lead of meter to one, black lead to ground. Set bias. Repeat for other slot. Thanks!
