I took this dead 1959 Silvertone, model 2202, transistor and brought it back to life after troubleshooting dead and missing transistors, broken circuit traces, bad capacitors and a dead speaker.
The audio circuit with the dual secondary driver transformer and transformerless output was quite commonly used in high fidelity amplifiers as well during the germanium transistor era.
Great job, Frank! With the old transistor radios that have zero sound, first thing I always check is the earphone jack. 90% of the time, someone shoved the wrong plug in them and bent the cutout switch. Or the switch terminals are corroded. Did you check the voice coil wires behind the terminal board on the old speaker. Some times those are broken and, if you are careful enough, can be repaired.
I just purchased another one last week, (the green one of the series) and it works. Arvin smartened up and made a bigger battery compartment for this one as it takes a standard 9 volt battery.
