Will this tube work in a tube swap?

I started this on a different thread, but I thought it was appropriate to start a new thread.

Will an RCA A48ABE10X (19") be usable for any monitor for a tube swap? I can't tell if the character before the X is a zero or a letter O, but it looks more like a zero. Can it work in a G07, 46xx, 49xx, or even a b/w or vector? 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. I know a 49xx is 9 pins plus the spacer. Thanks in advance.

According to this manual, http://www.bkprecision.com/support/downloads/pdfs/CRT_Setup_Chart.pdf

It is rejuvenated with a CR24. A CR24 is the same adaptor used for the WG K6100 color vector monitor. I am not sure what the pitch is for that monitor, you should be able to identify it by some raised numbers on the tube somewhere.

I would like the neckboard with CRT adaptor if you aren't using it. I use them to build rejuvenator adaptors.
 
Did that come from a TV, and if so, can you give me the make, model #, and any other relevant info you can provide on it? Also can you get yoke readings?

Shoot, I already gutted the cabinet it came in and threw it away. I'll try to get any info I can from the tube and chassis (which I still have). I'm glad to get you the yoke readings if you can explain to me how to do it (sorry never tried messing with swapping yokes or tubes before).

To measure the yoke you set your meter to read resistance and place it across a matched pair of wires, typically at the connector that attaches to the chassis. The colors can vary as to what is matched but you will know you are in the right place when the resistance changes. Record the resistance from each pair of wires.
 
To add to what he said, the yoke has 4 wires. In almost every case I've seen yet, the horizontal coil is always red and blue (in my experience). The vertical coil can be any other two colors, so put your meter on resistance/ohms, measure the ohms across the red and blue wires, write down that value, then meter across the OTHER two wires, whichever colors they may be, and write that down.

Any numbers or names you can get off the chassis or anything to describe the tv would be good. I'd also check the tube itself to see if its a 100 degree tube. The back of the actual tube has a number embossed on the glass, like 19v90 or 19v100. See if you can find that number.
 
So if an old tube uses the same rejuvenator as a newer no-burn-in tube then it can be swapped with no issues so long as you bring over the old tube's yoke?

I have a WG K6100 vector monitor with very bad burn-in. So according website, the 19VLUP22 (K6100) uses the CR24 adaptor. I found a new tube - 19VLQP22 that is a 100 degree tube. I was hoping I could put it into the vector. However, the tube uses a CR20 adaptor. Does this mean I cannot swap it over?

Thanks,

The swap should be do-able but you would need to find a way to adapt the 6100 neckboard to the new tube. I wouldn't personally try this swap...
