[Hallicrafters] Tube testers

[rbethman]

I agree with testing in circuit.

However, I too have one of the Western Electric Hickok LS-6XXXX-X testers.

I have found it to be awfully darn good for testing.

I've yet to find it telling me lies!

The 6000 actually has 2-different plugin sets of tube sockets and 2-different roll charts which allow testing of tubes from 01A to compactrons.  However, I seldom use any of those tube testers and usually just substitute tubes in the actual unit.
