I did replace just about all those resistors on that deflection circuits. On the tele-tone tv, B+, B++ and B- all measured within 5% of their Rider manual specs. I was kind of surprised by this, but a good surprise. I still have to verify on the Hallicrafters.
On both sets, the deflection amplifiers just seem to be running out of steam. They will amplify to a certain point until the image bunches and folds over a bit. At this point on both sets, I could get the image just to barely fill the masks, but it would be nice to figure out how to get some headroom
