I have no schematics for this radio, President McKinley. It squeals when the volume is turned past 1/4 as if there is feed back. Do you think it's a receiver transistor? any tips, ideas? TX works fine. Does it with external speaker as well.

Im sorry not receiver but audio amp transistor. Radio tx's and rx's good it's just the volume when turned up that causes squeal sound.
