James Sweet stated so wisely:

They're CRT's like any other and can hold a charge, but you're just
dealing with the yokes, not the HV, don't worry about it. You're more
likely to shock yourself trying to discharge the CRT's than if you
just leave that part alone.

AAaahhh...now I get it. I misunderstood you the first time. That is a
simple check. I'll check it and get back here to let you know.

Thank you,
Tom
