The TDA Used was a TDA1675A (IC901), according to the pdf of the chip, the RC combo you describes is as follows (R226) it’s a 1k ohm resistor followed by (C907) 1000uf 16v capacitor. The capacitor then runs to ground which is what I think the series you refer to as your combo. Sorry I have no schematics so im tracing along. Now I know pin 1 is my amplifier output on the chip thanks to the pdf I have. The cap is new due to a cap kit and the resistor although is a 1k ohms resistor, it reads good. They do go through my yoke hookup. Now the “pump up/boost” Diode you refer to, I’m assuming is off Pin 2 which is my Amplifier supply, the diode is (D902) 1n4002, which also reads good. Please correct me If I’m going in the wrong direction. Is a bit tricky without a schematic. Also you think I can use a Sharp KTMF chassis with this yoke. I need to fix this game asap for a location.
