This is the final video of this project. :-)
For this project I restored a 1930s radio but instead of making it play AM stations, it now plays Bluetooth and music of it's era. But, the music is tuned in using the radio dial just like it did back in its day.
The tone knob has five selections:
1 = Bluetooth
2 = 1930s music
3 = 1940s music
4 = 1930s Christmas music
5 = Orson Welles War of the Worlds broadcast
Radio is a Philco 37-11 made in 1937. 5900 of them where made and had a 7 watt amp. The original price of the radio was $150.
I used a Pyle PFA330BT - 90 Watt Bluetooth Wireless Streaming Stereo for the amp and a Raspberry v2.0 to play the music.
All code to play the music was done in Python.

Frequency Range of radio when it was original:
Band 1: 530 to 1720 Khz
Band 2: 2.3 to 7.4 Mhz
Band 3: 7.35 to 22 Mhz
Philco 37-11 is a Superheterodyne with automatic tuning and magnetic tuning control. Uses a push-pull pentode audio output circuit.
