Do you think the Vibrator could be bad? Also what's the purpose of those Vibrators in these old battery radios?
A vibrator is used to convert DC to a form of square wave AC to operate the step-up transformer. It also has a set of commutating contacts to convert AC back to DC. Eliminates the need for a rectifier tube, really old technology.
The vibrator's probably stuck and will act as a dead short.
You'll go broke, fooling around with lantern batteries to power this set!
