Ok so I have a theory the high voltage across L42 my theory is that the voltage on the path of the 470pf cap which goes to v6 as well as the 2.2 cap coming off the agc pot both those voltages come from the flyback so if infact there is still a problem with v6 then I think it’s safe to say the tube is not conducting correctly if any at all because if it were conducting then I think it would relieve excessive voltage at L42 because right now it appears to be solid standing voltage on both sides of L42 780v. That may explain why removing one lead from each cap having no change and still heating L42. Which in turn possibly shutting down v1 having no snow on screen and no video.
