Question for you tube swap experts...
I've got a couple spare Tovis/Happ ProVision MTG-2901 chassis and WG 7302's, these are nearly the same...
A couple of them are the fat 10 pin neck (CR23 I believe)
I found what I thought was a suitable tube. Samsung A48KRD89. It measures at the yoke - 1.8 ohms and 11.5 ohms
However both chassis produced an image that was just too big width/horizontally and in fact when trying to adjust the image, if you went too far the opposite way it would cause the chassis to go into like HV shutdown and the image would lose sync and you'd have to power cycle. So is this an issue of the yoke being just a little bit out of spec in terms of compatibility? I was assuming it was just a yoke that was either too high or low impedence for the chassis.
I found another TV, ended up being the same tube, looks like a newer version. Same model #, Samsung A48KRD89 and it measures - 2.2 ohms and 13.5 ohms
Wondering if this will get me more in line? I've been trying to read and figure out which direction that measurement reads on the Horizontal side that would affect width.
If anyone can chime in. I would appreciate it.
Thanks for looking/reading
