Driver Tubes 6922


I've heard a few people opining that the driver tube can be the most important tube.

Why is this?

What do you look for in a 6922?

What differences might I expect to hear replacing my modern GL e88cc with an expensive NOS 6922?

Any recommendations for a 6922  based on actual experience?

 

Thanks

Those testers are 60 plus years old so I'm not expecting true accuracy.   I want to test for shorts first and foremost.    That's what will damage your gear.  

Tomcy6, you are dead on.  No one tracked the tubes that were in those caddies.   Repairmen had tons of tubes on hand.   It was common practice for a tech to replace all tubes ,  that way much less chance of a return call.   What happened to the tubes that were pulled?  They went back in someones caddy and the bad tube was tossed.  

My tester is within 50 microhmos of a 6L6 and 12ax7 that were tested on an Amplitrex so that's good enough for me.  

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.

I didn't buy it just for that.  I test all parameters .   I was lucky and found d 9ne that looks like it was in a museum.  It was serviced a few years ago by the previous owner.   

I'm sure Andy is a good guy and reputable,  but if I bought tubes from him I would test them as well.   As mentioned earlier my tester is fairly accurate enough to verify I'm not getting screwed

Thanx for the info. Hopefully I wont get addicted to NOS, I just want two sets of AT7, AX7, 6922 and hopefully I’ll be set for life.

 

As to NEW, I am actually not that hung up on that. I’m annoyed that people list items as New Old Stock.....and they are not new.

 

How hard is it to say, "I sell used tubes I pull out of old radios. They test New and they’re awesome."

Thats how to do it. What if I sold a used scarred Mac 275 on Audiogon and I list it as NEW? That wouldn’t be right. But if I sell used tubes, I can call them new? Doesn’t make sense to me. Again, I don’t care if they’re used, but don’t piss in my ear and tell me it’s raining.

 

That’s all.
