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.

Don't freak out.
The high voltages are inside the box.
There's nothing to be affraid of arround the bias probes as you will measure there only milivolts.
275mV in triode or 290mV in ultra-linear modes.
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!
In some of VTL models there's one extra bias pot which is called Master Bias that regulates the bias current on all of the tubes.
In some tube models designers would place an extra bias pot onto each PP pair of tubes to adjust them both and each one independedly.
The red color leads on your voltmeter should touch the bias slots and the black color lead should touch the ground or chassis. You may also connect the black color lead onto your ground binding post.
