There is also a mica under the 12sn7, horizontal sweep, don't know if you changed that one but if you didn't be careful when changing make sure it's the right value and don't make a mistake putting the legs back in the correct position otherwise the horiz won't run and it will burn up the horiz hold pot. At one point I had changed the resistor to get vert to lock only to realize that I missed a mica in the verticle section and once changed I put back the right resistor and it was fine. Look in the schematic at the vert and horiz section and write down all the caps that are marked MMF those are the ones to change. The one under the horiz tube looks like a dogbone. Although some look like dog bones and others look like a domino.
