In a situation where the vibrator is not operational or not repairable a filament transformer with adequate voltage and current rating can be substituted in place of the vibrator. I did that years ago with a Buick radio from the early 1950s. It made a nice sensitive AM radio with good selectivity and more than adequate sound using a 8 inch PM speaker in a separate cabinet. There are ways to repair the vibrators as long as the precious metal of the contacts are not worn completely away or the reeds not damaged or fractured.
