No doubt, they are noisy rascals, hot too. Geoff, I'm glad you
mentioned 450TL. I have one I acquired with an old BC-610 someone had
hacked up trying to make an amplifier. Is there a way to test more than
the filament other than putting it in a working amplifier? I'd kind of
like to build something around it, but would hate to get it all complete
only to find the tube was too weak or dead.

The transformer I had (which ultimatly went back to Ronnie/W5SUM when he
got my 450TL's) was labled a "Sola Constant Voltage Transformer".
90 ~ 150v input, 7.5v ouput @ 42amps.
I remember hooking the thing up one time, to check some tubes (450's)
and with just the primary connected, the durn thing was 'noisey'. Made
noise, just sitting there, with no load. Noise didn't change with a
load, either, but that transformer sure did lite up a pair of 450TL's...
7.5v @ 12amps, each.

A: Yes.
Q: Are you sure?
A: Because it reverses the logical flow of conversation.
Q: Why is top posting annoying in email?
