[R-390] Testing tubes r392

[Glenn Little WB4UIV]

Is the R-392 working?

If so your tubes have been tested by the best tester available, the 
equipment that is using them.

If the R-392 is not functioning, do you have a service manual?
If not this should be what you get next.
I would then isolate the defective stage(s) and check the tubes that 
are possibly causing the problem.

Any standard tube tested that has setup information for the tubes in 
question will work.

A mutual conductance tester would be best.
