Questions about tubes and gear that glows. FAQ

RE: Cetron has a fascinating history...

Thanks. I'm pretty much a complete idiot about electronics, but I'm fascinated by tubes, and I'm planning to start soldering stuff soon.

That sort of answers my question. Does "acquiring" a tube type imply that Cetron's standards were more or less equivalent to Tung-Sol's? (I ask because of the things one reads about the material differences in JJ vs Tesla, or the New Sensor "Mullards," etc.)

If you don't mind sucking me a little deeper into all this, could you explain the Cetron codes?

Reading around the metal base:

7236 / Made in U.S.A. 105 A 72241 / 8049

I'm guessing 105 is a manufacturer code, but I can't find it listed anywhere.

Is 72241 the date code with a shift number, or is 8049 the date code?

In either case, did the quality of the Cetron remain near the level of the Tung-Sol, which I understand from all the sales pitches, was the best?

Thanks
