Ok the voltage is at 8.35 volts at the crt using a 49 ohm resistor across the heater. 52 , 56 , ohms the crt voltage is to high lower then 49 ohms is to low so this was as close as possible. 42 ohms were around 7.3 volts. So I settled on the 49 ohms. I also took out the 10 ohm power resistor and replaced it with a 22 ohm because of the diodes. B+ is 265 v the norm is 255 v so I think is close enough. Just have to find which can to adjust to remove a buzz in the audio and find out why the top of the screen is like a bright line across like on modern tvs the wide screen ends befor the top and bottom but it's the top that is bright on this set. It might be verticle.
