[R-390] Tube Tester

[James A. (Andy) Moorer]

I have an EMC 215. You can get them for $10-$25 you-know-where. Many tube 
nuts poo-poo them as being crass cheapo commercial units, but I have yet to 
find a case where it reads anything different from my TV-7 or my TV-2.

The construction on the inside is not very rigorous - for instance, they use 
the infameous "flying joint" soldering technique in a couple of places. A 
few minutes with the soldering iron will put all these right.

The list of the tubes they test is quite complete. To do some of the 
transmitting tubes, you need an extension box which is a bit harder to find. 
I have only found a couple of tubes they won't test, and nobody else tests 
them either (like the 9556 UHF triode).
