I have been working on a Philco 40-115 which needed to have almost all the rubber wires replaced along with the capacitors, it was labor of love for sure. I was pleased that it worked at all. My question is does anyone worry about the modern line voltages on these AA5 Philco radios. My line voltage is around 125 volts and if I add up all the tubes and the pilot light I just scrape in at 101 volts. There is a filament dropping resistor candohm that is dropping the voltage some. I did some voltage checks and the radio is running about 10 volts higher than the schematic voltages. I measured these with a modern meter and an old analog Simpson and they are around the same.
I have worried about the higher voltages with transformer based radios and do drop the voltage for those. This radio will be returned to the original owner and I have no idea what kind of line voltages they will have.
Thanks for reading!
