high voltage loss

[timmy]

well i got a total of 16 caps and replaced them and got no more hv then i had befor so now im really at a loss as to where to go from here. i was thinking the horiz oscillator tube 6cg7, the resistors and caps around that area, would this possibly be a cause for low hv. the cathode current on both horiz tubes are where it should be.bright down is 16kv bright up 10kv alittle lower to clear the screen is 12kv much to low. tried 2 new horiz output tubes and a vert output tube rectifier tube and hv regulator tube and still no difference in the hv, still to low.this is baffling because certain things removed to check hv usually raises the hv but nothing at all raises it.resistors i checked so far are right on where they should be. the remaining tubes in the chassis check very good so if anyone out there has any idea what i may be overlooking or what i should be looking at i would sure love to here from you,lol,lol because at this point i dont want to give up. i think if the fly was bad or going bad then with the high voltages in the fly it would have self distructed by now and the cathode current would have been threw the roof if shorted but its not.
