I have a Hickok 600a that had the 83 replaced with regular diodes. I was all concerned about that, but other than a sticky meter, it works ok. Calibration voltage seems pretty close. May not be perfect, but does tell me if a tube is good or bad. They probably recalibrated it so that it works decent. I also have a Precise 111 that will has verified a tube if in doubt.
If I could find the place called "Somewhere", I could find "Anything"
