[SignalOne] 8072 Final Tube

[Don Merz]

 Transmitting tubes can rarely if ever be tested by commercial testers. Sometimes you can rig something. But usually the voltages and currents involved are higher than what a commercial tester will safely handle. 
The 8072 is about as robust a tube as was ever made. The chances of it being bad are small enough that it is a pretty safe bet to just test it in use. Just my opinion. Your mileage may vary....

I have a EICO 667 Tube Tester and the latest tube listing - no 8072 tube is listed.


Anyone know how this tube cam be tested?
