Perhaps I need a little clarity Lets called the XXL closest to the IF transformer the Mixer tube and the XXL at the end of the chassis the Oscillator tube, these are the functions they perform.
So currently (a little electronic pun there) the voltage on pin 2 of the mixer tube is? And the voltage on pin 2 of the oscillator tube is?
Just want to be sure that where on the same tube rather than calling them the 1st or 2nd tube.
OBTW if you want a schematic that is easier to read (Rider's is awful and the philco service info not that great either) the 41 model 41-260 or 265 are very close to what you have.
