1955 Granco FM-610U Tube Radio (pics)

I have fixed plenty of speakers with the water trick. Get some water in a cup. Using your finger or a small brush, dampen the whole cone. Keep water out of the voice coil area. Set the radio with the cone facing UP towards the ceiling and let dry overnight. Be sure it's completely dry and try it the next day. You have nothing to lose.

I'm going to try that trick! I have a Zenith 845 series, with the 8" bass and midrange speaker. The voice coil has a real slight drag, only heard at low volume.
I think it should be allowed to air dry and not force dried, as by a hair dryer or such.
