[ARC5] Testing 1625s

[J. Forster]

Hi,

I have some 1625s and would like to test them. I don't have a tube tester
available, but do have the required filament and plate supplies (0-600 VDC
@ 1A), a good 'scope and an audio generator.

Does anybody have a link for the setup? I'm mostly interested in a simple
Gm test, but leakage/gas would be usefull too.

I don't have many tubes to test, so switching between them is not needed.

Best,

-John
