i found a reference in the sams that the chroma reference osc is .2 volts and looking at the schematic a test point shows 30volts on the #7 pin so i guess 50 volt cap would do but how would a 22pf be instead of the 6pf ?

If it's a timing cap in an osc. circuit then changing the capacitance is a sure way to mess up the circuit's operation

oh great, lol, i dont know, time to toss this set out the window and into the fire pit.....does anyone know if this cap would compromise the timing, i just want to put this thing back together and leave it now...

ok an update on this silvertone, i found that after changing the 1st@2nd video tube the lines are i would say better then 90% gone, but of course i still have the hv that just wont regulate. for the 6pf cap i used 2 50volt caps rated 2.2pf and 3.9 pf in paralle to make 6.1. and the tube was the 6aw8a for some reason it is much, much better unless there is an issue in that area and being each tube is somewhat different then another maybe resistance was somehow corrected if this is a problem there. the hv not regulating is very weird as i again tried several reg tubes and also tried a solid state 3a3. also checked the crt ground and its fine so i guess its leave it alone for now. could the crt be gassy but still show it tests good and not show a purple glow in the neck and still produce a good pic but yet effect the hv in a regulating way ?
