On the Rider schematic for a 37-630 [PHILCO, pg 7-57], the capacitor/resistor pair on the cathode of the 6K7G I.F. amplifier tube is 0.05uf and 400 ohms. For a 37-640, it's 0.25uf and 700 ohms. But my 37-630 itself has a 0.25uf cap and a 400-ohm resistor, both apparently original. Should I go with the schematic for the 630 or use the values in the radio? Or does it matter?
Thanks
