By far the oldest radio I had repaired. The Atwater kent model 10a is a TRF
(tuned radio frequency).This was a popular design before the advent of the more sensitive and selective super heterodyne radio. I only had to replace one of the audio amplifier tubes and do a bit of cleaning. As far as I know, it probably hasn't been turned on in over 70 years.
