[Hallicrafters] Tube identification - thanks.

[Waldo Magnuson]

I've been able to identify the tube in the power supply (0A2) with the 
help of the forum people who responded (Thanks Jack, Ian, Walt, Dick, 
Gerry, and Paul).  The suggestions really helped.  Measuring the 
internal interconnections and using my hot breath, a magnifying glass 
and strong light solved the problem.  It turns out the 0A2 had a 
resistor in the wrong place so was not regulating.  It is identified, 
fixed, and operating now.  Thanks for the help.
