John, unless someone has added them in, you won't find AC line caps in your Philco 50. It's a good idea though to connect Y safety capacitors to each leg to ground of the primary of the power transformer. It reduces line interference which there seems to be a lot of nowadays. Add the switch side after the switch so they are not in the circuit until the switch is turned on.
