Tube Tester for 2A3

I assume that since I usually buy matched tubes that they will go bad at the same time, so matching is not a big concern. But if I can get a used mutual conductance tester for $150, I will be go for it. Any suggestions will help me. thanks

Not necessarily a valid assumption, Ykk, but also difficult to buy a single that matches what's left if one tube is shot (failure or wear) and the other is OK.

If you can get more than one, email me. I've been looking, and prices are going the way of NOS tubes. The Transcendent Tube Analyzer is something I have been looking at, because it will test about everything, and if I am going to spend that kind of money it looks like the way to go, because it does this:

The Transcendent Tube Analyzer provides the tube parameters needed for your exact application. A tube's operating characteristics can be accurately determined for your specific circuit or equipment. The heart of the Analyzer is a sophisticated adjustable power supply utilizing a tube-based differential amplifier. It can be set from 300 volts all the way down to 0 volts. Voltage adjustment is made through a 10 turn potentiometer for very precise settings. Many tubes can be operated with as little as 25 volts on the plate and the Tube Analyzer allows for the determination of these parameters at these and other voltage levels. The ability to set the operating point virtually anywhere allows circuit designer or hobbyist to be able to understand exactly how the tube is operating and take advantage of this knowledge in the design or operation of a circuit.

I know it does a little more than you are looking for, but I think it may be the way to go for me.

Just thought I'd pass it on.

I see. So I better look for either mutual conductance tester or the transcendent tube analyzer. I know Hickok and BK Precision testers are used by some, such as the 539 (?), 600, et al.

Jphii, is Transcendent Tube Analyzer the brand name?
