I do have the 38-15 schematic. What I have found is there are several resistors not in the schematics. Or I'm not able to read the resistor's.
If you look at where the two what I think are 1M ohm resistor's on the 75 tube socket. I can not find them on the schematic's.
Where the 1M tie together he has attached a pf cap that goes to #15coil.
I get the 250K red dog bone taking the place of the 190K is fine.
What I have found as well is I don't have a 78 tube but a 6D6. Because on both sides of the 6D6 someone increase the resistance. Looking at the 6D6 to see the difference between it and the 78.
Is this a Mod to use a 6D6 instead of a 78? Did Philco send out a recall notice? This does not look factory at all.
Still verifying the Caps Mr Rossi the first 16uf cap on the left of the bottom of my pic is a replace for the 12uf. But he went to ground with one side pics will follow because this is interesting too.
Above is a post of the bottom of my chasis with what I have identified. I have provided copies of the tube positions too.
