Bluetooth Speaker in a Philco Jr. Radio.
I was gifted an old Philco Jr. radio from the late 1920s. The
original capacitors had corroded away. After removing the
internals, I found that someone had tried to fix the device. New
capacitors, fuses and wiring were done sometime in the late 70s.
One of the caps ran from the power line directly to ground.
If this had been plugged in, I think the whole thing would have
caught on fire. The wood cabinet is in really good condition. It
looks really nice. I really want this to hang out on the
shelf. Since the internals were in bad-to-terrible shape, I
decided to convert it into a blue tooth speaker.
