Heath tube tester TC-2

[Donald c Voigt]

printable

I need to check some old tubes, 2A3, 45, 26, 30  etc.  But this Heath =
checker I borrowed does not have listings for these old tubes.  Are =
there any charts or lists that would have the settings for these older =
tubes?   Don Voigt.  w4hqf at peoplepc.com
