Great radio. You need a band switch knob which is pretty easy to find at swap meets.
I changed the selenium rectifier to a 1N4005, replaced wax/paper caps and tested the 2 electrolytic caps.
I added a CL-90 thermistor (from allied radio) to limit inrush current to tube filaments and rectifier.
Band switch is touchy even though I cleaned it with DeOxit. So bad I had to jump out (hardwire across) two oscillator switch wafers.
Its a daily driver and oddly, it works quite well and is selective with the built-in "cord loop" FM antenna
