I accidentally reversed the polarity of my DC power supply. I blew
the fuse in my TNC, but I can't find a fuse in my TR-7400A and the
only fuse I see in my TS-520 appears to be for the AC power supply.

What sort of damage could these radios have suffered?

You may have blown the 'idiot diode' as well as the fuse..
