[Test-Equipment] TV-2

[appo2 at juno.com]

There are many power supplies available to test tubes,,,I have many old
Fluke,,and later B&K solid state 
unit,,,you can check any tube 's GM,,,,use the tube as your reference if
tubetesters denote GM,,but most
tubetesters' are Go or No go.Thus any good tube is a reference.
