Re: 600 vs. 600A (Hickok).
I was able to find the settings for the older tubes online
for my 600A.
I can test 01A's, 24A's, 26, 27, 42, etc... The settings are not
on my roll chart but they are available if you search online.
The 600A does have the 4 pin, 5pin, 6 pin, 7 pin older sockets.
It does NOT have the newer compactron type sockets (11 pin etc...).
The 600A does test for gas in amplifier tubes (not rectifier) and
it will test for shorts and it will also test balast tubes.
They dropped the older tubes sometime in the 60's from the
roll charts because they didn't have room on the chart.
