I have a G-A48ACB02X tube that tests good using a rejuvinator.

It was part of a "take all my 19 inch monitor junk for $100" buy made last year. It included a number of G07 and WG4900 chassis, as well as some I don't recognize (they unrecognized ones all look newer, I was told some may be VGA).

Its in a frame, has a WG serial number on it, which matches the chassis serial number from the frame... but no chassis.

There are various WG labels on it... but no monitor model number.

The yoke resistance readings on the Red & Blue wires are 2.7ohms, White & yellow are 6.8ohms.

Any insight into what chassis was likely originally on this monitor, and what chassis are likely to work with this monitor?

I've been searching around and have some thoughts, but I'd appreciate some expert advice. This tube is pretty clean and I do I have need for a monitor for a Gyruss cocktail, and if I can get to that with this tube then I'd consider that buy a success :)

Pretty comfortable repairing monitors, but haven't done any tube swaps...which I suppose is what I'm trying to do, only in reverse :)

Various photos attached. Please let me know if any other info would be helpful.

It could be a medium resolution K7000. What's the number on the yoke sticker?
 
edit: paul400 and M L K likely have it. At first thought without seeing the photos the tube number seemed similar to something for a k4600.

I have one like that. It's not a med res k7000. It's a 15khz one, but the vertical yoke has an impedance and inductance about half that of the earlier versions and there are a couple of resistors in the vertical deflection circuit that have different values.

Did you ever figure out which chassis goes to this yoke: 9A2919-001?

I have the same set-up, very nice burn free CRT, clean yoke and rings but no chassis....

It is also a 10 pin neck but a different diagram.....
