Polarity reversal

I assume this has been covered before but I'm not finding it.

My "new" '55 400 has undoubtedly had the battery connected backwards in the past by people not realizing it's a positive ground system. I repolarized the generator to correct the charging issue but find that the radio is dead. I seem to recall reading somewhere that is a common casualty of reversed polarization. If so, what specifically is damaged? Is it typically the vibrator (which is not vibrating)? The fuse is okay.

Any other damage that may have been caused?
