Thanks John,
The osc trans has been replaced. I too feel that it should be running close without feedback from the HOT or sync. Oddly, if I try to "jump in" some experimental values the frequency dosn't change much at all. Can,t even drag it closer to any great degre.
All r's and c's and micas have been replaced, tubes swaped and even original Rs and Cs checked to make sure the schematic dosn't show different values. B+ is very close. I don.t suspect socket leakage esepcialy at this frequency, it's not like it's RF and the socket looks OK. I can tease some voltage off the HV rect with an insulated driver but very low level. At one time I could see a line up the screen in a dark work area but with it soo off freq I'm sure the DY and HOT are not resonant, hence the line. I disconected the yoke wires and put a frequency generator across and got some raster so I believe the DY is OK. Really strange.
