tube tester data for a few oddball tubes
#1

Hi guy's,
I have a Hickok 538A tester and have a few tubes to test which are not listed on the tester.
I need to test a 42 tube, a 37 tube, and an XXL tube, none of which are listed.
I know there is a website that lists the settings for this tester, but I cannot find it.
Anyone have any info?

XXL = 7A4

that's all I can help with on this, though! Icon_smile

Go here and then select Hickok for all kinds of downloads and things.

I don't know what number chart you have but here's part of a Hickok bulletin that may help.
