I have a Heathkit IT-17 tube tester and
need some information from anyone who has
a conversion chart for this model. I don't have
the tester with me, so I'm not sure if the tubes
I'm going to list are on the roll chart.
Most of the ones I need to test aren't.
I need the settings to test these tubes:
6A3, 37, 42, 76, 77, 78
TIA for any info......

Here are the settings you require. I have a Booklet for the Heathkit IT-17, It-21 and IT-3117 tube testers dated 1979. Tell me if you need a scan or copy of it.

Tube Type Fil Plate Top (T) Bottom (B)
6A3 3 6.3 28 BC D
37 3 6.3 37 BC DE
42 3 6.3 29 BCD EF
76 2 6.3 33 BC DE
77 3 6.3 30 BCN DEF
78 3 6.3 31 BCN DEF

Thanks to Ross for the timely reply!
Can't wait to get them tested and
start restoring the latest project,
a Philco 116X.
