I have an old STS AV7600VOR handheld nav/com radio. It has a problem in the audio stage (it "motorboats" when the volume is turned up to any usable level). I have the owner's manual, but it does not contain a schematic or any service info. Does anyone out there have this info? STS is long out of business. Internet searches have only located other people in search of help. I don't want to junk this radio because it's otherwise in working order.
