Today I finished replacing the electrolytic sections in both can electrolytic capacitors in the power supply. There were two, a small one P/N 30-2570 which consisted of two sections tied together, a 25uF@450V and a 10uF@450V with a 10K 2W resistor going back to the triangle section a 10uF@450V of the large can, P/N 30-2556, and a Philco Power resistor P/N 33-1336-51 from the small can to the 25uF@450V half-round section of the large can, P/N 30-2556. When I was removing the large can electrolytic I discovered that its ground twist-tabs were never soldered at the factory. Not a single twist tab of the large electrloytic had been soldered to ground. I made sure that one of them was soldered to the chassis this time. It may not have caused a problem, but better safe than sorry.
Next come the replacing of all the paper-wax-foil capacitors in the set. some are in tight spots, but nothing looks too difficult.
