Driver Tubes 6922

I read about a test someone did on the web, that had several calibrated Hickok testers and got a different reading from ever one of them.

Why would you spend the money for a Hickok tester just to test a tube for shorts, a much cheaper tester can do that.  You should just buy tubes from Andy from vintage tube service, I've never heard any complaints about his tubes, but I have about everyone else's tubes at one time or another.

@tonydennison  would you consider a tube as new if has been tested over the years hundreds of times, but never used in any equipment.

@tonydennison  no, but just wondering how you would be able to tell if a tube has never been used? I don't think you can tell, by the boxes or the printing on the tube itself.

@tonydennison the problem is you could buy those tubes you consider new and they may not last or test as new.

Then I guess all old tubes should be sold as used, because there is no way to tell.
