rejuv tube list - more up to date list

[TheShanMan]

The tube list that came with my bk 490 rejuvenator is dated somewhere around '90 IIRC, and when I've gone to check out tubes I've found a couple that aren't in the list because they're newer. Rather than having to decide if it's worth taking a chance on the tube, is there a list of tubes that is more up to date than mine online somewhere? Or does anyone who has a more recent hard copy want to volunteer to scan the A48's?

I'm not talking about the small list of "these tv's are good for tube swaps" web pages. I'm talking about the "exhaustive" list of tubes that comes with a rejuvenator.

This is the most recent one I know of:

This is the newest list I know of:

Thanks guys! Too bad those pdf's aren't dated. But on the plus side they are newer than my hard copy because the TV I decided to take a chance on is in those pdf's and the tube (a48aab13x) is a cr23.

Unfortunately those pdf's don't let you copy the text, but I created a one page image with all the A48's and 19's so I can take a single sheet with me. Figured I'd post it in case anyone else wants it. You can do a double sided print with this so you only have one page to carry around as you look for tubes.

Does this info mean that it's possible to swap a 19VLTP22 tube with a 19VMRP22 tube?

If the pins on the neckboard match, could I just swap chassis without swapping yokes?

Yes.

No. The yoke is pretty specific to the chassis, you have to check the resistance of the windings and compare it to the one that's supposed to go with that chassis. Sometimes you get lucky, and they're real close, and swapping them will work. Otherwise, you have to swap the yokes. The yokes are not made by the people that make the picture tubes, they're made by whoever makes the monitor. So, while the tube itself might be the same, the yokes are all going to be chassis-specific.

Yokes are chassis specific and tube specific. So using an arcade chassis' yoke on a "compatible" tube will not necessarily yield a picture that you can get converged. Success with this approach will be very hit and miss - more "miss" than "hit" in my experience.

This is true - but the only way to find out is to try. I've had pretty good luck in the past. It is hit or miss, sometimes it's hard or impossible to converge it. Other times it works fine. I can get an acceptable picture most of the time though.

But, if the tube has the correct base pinout, it'll work in the sense that it's compatible electrically with the chassis. You will get a picture. Getting it converged is secondary and isn't always possible.

I'm currently enjoying a 100% success rate. I've only done 2 of them, but both worked perfectly and needed minimal if any convergence. Both were K7200's.

What if both tubes are from arcade monitors? Would it mean a higher probability of working, versus using a compatible tube from a TV?

I am learning that some tubes that start with 510 might work as well.

Very helpful! thanks for posting this.
