tube swap neck compatibility question

Cleaning out the garage and came across a 19" TV with an RCA tube. I check a WG49xx monitor that I have lying around with some bad burn on it. It's an RCA tube too. Different model number, but who knows. So when I pull the neck boards, the 49xx neck has 9 pins (plus one additional "spacer" pin). The TV neck has only 8 pins (plus the spacer pin). Ok, I guess this is a no go. But before I toss the TV tube, do any of the common game monitors have an 8 pin neck (plus spacer pin)? Like a 46xx or a G07? Or something else? Thanks.
 
There is a good chance it will work if it's a 29mm neck. Is the last pin on the right next to the key missing? The first and last pin next to the key is not used on the 10 pin tube.
 
Post the tube # and we can tell you.

I posted this in a separate post, but it is an RCA A48ABE10X (19"). I can't tell if the character before the X is a zero or a letter O, but it looks more like a zero. The neck is 8 pins plus the spacer pin. Someone asked which pin was missing. If you put the spacer at the bottom, i.e., 6 o'clock, it's the one to the right, about 4 o'clock.
 
Why would you post that in a seperate post?

Bad news...that tube crosses to a B&K CR-24 and not a CR-23. The good news is that, IIRC, it "only" swaps two of the colors (red for green) so if you built an adapter for your monitor that swapped the colors you'd be good to go.
 
You can use that tube with a WG7000 chassis although the yoke probably won't work.

I never tried tube swapping before, so you got me (easily) confused. Which yoke won't work? The one from the original (burned in) tube? On a tube swap, aren't you supposed to use the yoke from the burned in tube (and the convergence rings of the new tube)? If the old yoke won't work, how do I get around that?

He is saying that the yoke on the TV is not likely to work with the K7000 chassis. If you find a TV that you can reuse the yoke it makes the swap much simpler.

Test the TV yoke in the method I described in your other thread and compare the readings to the K7000 yoke.


BTW, you are right about the rings and yoke. The convergence rings should always stay with the tube and the yoke will almost always stay with the chassis, the only exception is if you find a TV with a yoke that is close enough to be compatible.
