[Hallicrafters] Re: Testing tubes

[Glen Zook]

There are some tubes that have a deliberate cathode to
heater connection within the envelope.  However, they
certainly are in the minority.  It is pretty unlikely
that all of the tubes have such a short unless all are
of the type that were manufactured as such.

I suspect that the faulty tubes all have heater to
cathode shorts, and you are seeing heater current flow
into the cathode circuitry of the tester.
