[Test-Equipment] Hickok CA-5>TV-7U tube tester info

[Bill Weinel]

Hi Ray,

The manual on this adapter, as well at Hickok tube testers, are all 
available at: https://stevenjohnson.com/hickok/data.htm

To use the adapter, you just need to match the pins on the adapter plug 
to the pins of the tube socket on the TV-7.

The knobs on the TV-7 are the socket pin numbers. For example, the first 
filament selector knob 'A-P' are socket pins '0-9'. The other filament 
selector knob works the same way.
So for testing a Compactron tube using the octal socket on my TV-7 with 
the CA-4 adapter, the settings on the TV-7 would be BS3-5478 where the 
adapter plug pins are:

1 Filament
2 Filament
3 Grid A
4 Grid B
5 Plate
6 Screen
7 Cathode
8 Suppressor
