This is my second successful tube swap attempt. Here is some info that might help someone else in the future. First, the wells 7302 19" chassis I have has a 10 pin socket (cr-23) and needs a yoke reading of 2 ohms horizontal(red and blue) and 14 ohms Vertical(yellow and green). I have a Orion t.v. model no. tv1929 that has a yoke reading of 3.2 and 14.2. So this should be close enough, but it has a 8 pin socket (cr-31). I started looking at the wells neck board and noticed two different sets of solder points, one for 19" and one of 13".(19"= 10 pin and 13"=8 pin). I needed a 8-pin socket for the Orion tube, so I thought what the hell I desolded the 10 pin socket and replace with the Orion 8-pin. Hooked it all up and I got a blue screen, so I wired up Mortal Kombat and had a good pic, but no green. After farting around a little bit I switch the red and green input wires and now I have all the colors and the picture looks great. Something I noticed on the orion 1929 there is a wire that plugs-in to the neckboard from the yoke with the degaussing coil.Do not ground this wire, all you"ll get is clicking noise from the chassis. Hope this help's someone.
