Does anyone know what bulb is the replacement bulb for the short indicator on a Heathkit Model TC-1 Tube Checker? UGH...

Thanks!

Probably a #44. Is it a push and twist or a screw type?

It's a twist (which I think is also referred to as a bayonet). Incandescent.

And it does look like the #44 is correct. Thank you folks for the feedback.

No problem. The #44 is about the most common light bulb for test equipment from that era.

After you posted that I looked it up and saw how common it was. Thanks again Adam!

Figured it was the #44, though I have had to change out a few of the old neons on those. I have an old TC-2 here and there is a neon for the power indicator that used to flicker on and off.

Handy tester, one of these days I need to fix it, apparently the guy that wired it messed something up because it refuses to range properly when testing 12A_7's. The meter pegs hard. That or the chart is incorrect. I never bothered finding out since I use my Mercury the most.
