You're right, of course.  This old analog meter will do 6KV but you
actually have to change the leads to the 6KV position.  I was reading
one scale and measure another.

It's not 5500, it's 1.5KV, which I take to mean that something is
wrong in the voltage multiplier circuit, I imagine.

Back to the drawing board...

Thanks,
Jeff/KD4RBG
