Philco 514 Questions
#12

Update: Installed the base of the cap. can with new capacitors wired in. While soldering in the wires on the bottom terminals I questioned the jumper wire from terminal 1 to 4. I didn't remember any external jumpers on the schematic. PANIC!! Maybe I had labelled the wires wrong or numbered them wrong. The answer was discovered on the schematic right above the power supply in the middle of the page was a 3 step note explaining the re-wire. On to the re-stuffing of the hum control caps and a new reproduction of the yellow Aerovox label which is on the back side when the can is installed. The new one goes on the exposed side. Now the toggle switch on the primary tap select of the power transformer crapped out so will have to replace it. Since the transformer is 90 years old I am considering dropping the primary voltage to around 115 volts with a dropping resistor so it won't work so hard. So, now I have to go find some brass wire for the tuning capacitor control.
