well yes it does fluctuates and its around 640 and turn the bright down and it rises to around 800, the more out of focus the less the voltage and its with white pictures that are bright. it clear its hv regulation but im stumped here as to where to go from here. i tried another 3a3, 6bk4, checked the 6cg7. grid voltage is ok at between 118-120v. this all seen to start after changing c2 and ce caps with separate ones for each with slighty higher uf and or voltage.hv stands at 24kv bright down and the hv adjust pot has no affect when turned.also tried another damper with no result. if its low b+ then why after the caps were changed or is it something to do with the hv pot not working.
