The one thing I notice is the vert out trans makes more noise than I have noticed in other sets and the primary reads 200 ohms higher than the 620 ohms its supposed to be. Anyone think that might be the problem? Any suggestions?
Thanks

All those RCA's needed capacitor replacement in the vertical sweep circuit. A lot of them were rather new, when needing re-capping. Either there was a non-linearity problem or the vertical hold control was on the end of it's range and still wouldn't lock.
