Problem is that this stuff is not mercury at least not liquid. There is
plenty of that also but I not concerned with that. It's the flaky stuff
clinging to the top inside of the glass that bother me. It is more like
ash but shaped like the anode as though small pieces of it flaked off.
There so thin and light that they cling to the glass and no amount of
shaking will get them to drop to the bottom and out of the way.
I had great fun now that it is all wired up and waiting for the
transformer. I hooked the 110v line through a current limiting resistor
to them and they glowed dimly but it was lovely. Took my awhile to
figure out why nothing happened when I hooked each side to one of the
plates. Without a center tap xformer, I can only do one at a time but
it was pretty exciting anyway.
p.s. I also need a couple more tubes if anyone has some for sale.
