This tv is making me nuts it's all recapped and yet I cannot find anything wrong, resistors are not perfect but are still in the area verticle output and oscillator transformers check good ohms. The oscillator pins 6 and 7 have no activity at all . Pin 6 has 7 volts which should be 90 volts and pin 7 has negative .770 volts which should be negative 26 volts pin 2 of the same tube output side has 25 volts which is ok having 21 volts . So it seems there is a clear problem with the oscillator section and I concentrated on that area resistors and find nothing. Where there supposed to be the high voltages there is. I subbed the hold pot, height, and linearity pots still nothing just a horizontal line. I'm sure the voltages are simply not there because the tube is not conducting at least I think that's the voltages that are in the SAMs as a working set. The SAMs I have is a speck different but everything I checked already matches the SAMs I have if a resistor shows otherwise I check it anyway. I don't know if the yoke is needed for the oscillator to run but I just as well look into the yoke although nothing is burned visually.
