Rick,
I don't use an SB-220 but I do use an Ameritron Al811 amp.
One more pointer besides the lethality of the voltages as the other esteemed
Steve mentioned:
You can speed things up from a tuning aspect if you mark the location of the
plate tuning and plate loading knobs. In your amp's manual, they may have
suggested approximate settings.

I think I'm beginning to see how it's set up.
Thanks again for your help, and 73.
