Philco 91 Restore Code ??
#11

Thanks Mike. I at least know why it is there if I don't fully understand it. I see where you talk about a cap and resistor in series. That shows as 47 and 47a in the NA schematic (code 126-226). Parts list says the cap is .006. Anyway I think that part is sorted out.

I remember somewhere reading that the cannedohm 900 ohm (pins 1 & 2) section may be wrong and should be 9K. The person did some tinkering and settled on 5K. I remember the person said the screen grid voltage was way too high on the 44 tubes and the 2700 ohm section was running way to hot. The change bought the temp way down and bought screen grids down to reasonable level. What is your thought on that?

I still need to get my output transformer and speaker wired in and a resistor wired in to replace the field coil. What wattage would I need for the coil resistor?
