I would try taking the filter network out of the original yoke and replace that for what came in the Y10. Looking at Riders schematic they show a 47pf cap in series with 1000 ohms. My Thordarson catalog shows only a 56pf cap there. Also make sure you don't have the yoke leads reversed. Ordinarily you'd catch a reversal because the picture would be mirrored, but it could be overlooked if you're focusing on other issues.
[edit] The filter network should be across the coil connecting the damper cathode.
