Your radio should have a 12BE6 for oscillator/mixer. These tubes fail to operate on higher frequencies but may still work on broadcast band.
Clean the band switch. Try another 12BE6. Be sure B+ voltages are high enough on this tube. Are you using an antenna?
50C5 is an audio output tube. It drives your speaker.
