pics,

the vert is still jumpy, I pulled the deflection board, reflowed some iffy looking solder (really not bad) including the socket for the yoke plug.

tested a few e caps since I had it off, one was a bit weak (power factor of about 35, again not bad but since I had it out to test I replaced it). reflowed some solder around the ground points (4 corners of pcb) cleaned the chassis at those points as well.

put it all back and it still is jumpy. intermittant jumpy that is, it will be fine for a while then kinda jump up from the bottom, not roll just shrink from the bottom a bit, then snap back.

I did reset all the transistors (sockets), but left the IC's alone, they where in real tight and I did not want to break anything.

guess I will pull it again and try checking some more caps. or maybe try some freeze mist to see what is going on.
