Yup. From what I can see, I would have to build a testing chassis with
the right setup for each tube type. Then crank it up and put a signal through
the tubes. Seems I'm not going to learn much with the meter but it 
was worth a try.

450 volts pah, it just bites a wee bit harder than 110 ;-]  I cheat 
(in a paranoid way) and
wear doeskin gloves when I play with this stuff. Also use chopsticks 
and a few other tricks
I was told about.
