Get it Working – 1947 Firestone Air Chief Radio
This 4-A-31 “The Rhapsody” Firestone radio had sat unused in a corner of our house for a decade. The same Firestone as the rubber bits on your car wheels.
Apparently it always used to hum a bit when my wife last used it…before we met in 2005 !!!
It doesn’t hum now 🙂
