B&K 467 rejuvenator service information available
jennifer:
The 467 is a nice machine in the overall scope of things, I had a few of them over the years, However after tearing them down for parts I noticed they easily swap over to the Beltron (which has no/little socket support or tech info) The beltron is a better machine IMO given it uses current not volts (as the case with the 465) to do the deeds...As result the Belton can fix or trash a tube the 467 won't even dream about.

Hi Jennifer,
I've never heard of the Beltron. Do you know the model number?
When testing the B&K 467, B&K 490B (Konig TR850), and Sencore CR7000; I noticed that the 467 definitely pushes volts during the rejuv process more than the other two units.
The CR7000 pushes the volts a bit: for 6.3v tubes, some restore functions will push the voltage to 7.5v, while others add half of the set voltage – so 9.4v approximately. The CR7000 also uses DC rather than AC voltage. The higher rejuv functions will push the current as high as 100mA.
Any ideas about my issues with 467?
Thank you

That was the 8080A... Not a lot of information on them, But they are certainly a beast worthy of mention.

How does the Model 2972-E compare?

Hi Ken,
I did another inspection of the unit and may have found an issue. Diode D35 (91v) appears to have be crushed and parts of it are cracked off. It seems to test ok, but I plan to replace it. It’s next to the one of the modules connectors so it’s possible it was mashed by it.
Do you happen to know what part of the circuit this is?
Thanks again for your help.
