Does anyone know if I can swap a A63AFW32X 25in tube onto the sharp image 320-A chassis? This chassis is currently in my big red neo geo cabinet and the burn in is bad on it. I was able to find the tube above from a free tv I found on the side of the road. The current tube inside has label with M06FD17, I couldn’t find any information on it.

The label in the second picture attachment is covered up by some part of the monitor frame. IMO that label looks like an RCA tube label. You likely will have to remove the monitor to confirm what tube model you have in the cab. I am guessing that the big red neo geo cabinet has a 25" monitor (A63xxx) like the tube you found. If so, then yes you can swap, but you may have to swap the yoke from the Sharp tube to the TV tube. I'd try hooking up the Sharp chassis to the TV Tube without swapping the yokes first. It may work out of the gate.

Best practice would be to measure the yokes (resistance and impedance) to see how far off spec the measurements of the new yoke are from the old yoke. 10% is a good ballpark. Post your results.
 
Measurements will be taken tomorrow but I did want to show the current burn in of the tube. Also I noticed that the monitor takes literally 2 seconds to turn on. Bad flyback??
