the B+ will drop as I increase the screen voltage go down as low as 80vdc. and is jumpy when the picture changes on the screen. replaced the HOT voltage reguator and capped it, also checked all the larger resistors in circuit and they seem fine. would the flyback cause something like this? or something else?
 
i would change it and see.

other wise until you rule it out we will not know.

i have not had or seen that problem before.:confused:
