[Amps] Supply question

[Sam Carpenter]

When you run the 3-500 easy, you will have a greater chance of arcs than if
you run the cherry red or orange. The gettering material is on the anode and
it requires color, sometimes significant color, to eat up the full range of
gas. I would venture to say that you may have less chance of arcing in a
higher voltage amp that is used regularly.

I understand that with 3-500 the 3rd order IMD gets pretty lousy when
the Ep gets up there much above 3 KV.

I also had some idea you get a much bigger chance of arcs in the tube
if you push the Ep way up there near the limit.

comments?
