Fades in and out, eh? I have an intermittent problem myself with those kinds of tapes. If I hit the foot pedal down to play, I will hear the first two to three words really clearly and then the treble disappears. It then sounds as if they are talking through a tunnel. If I bring the foot pedal up and back down again, I can hear again for another two to three words. This will go on for the whole tape.I've always assumed that those tapes need to be replaced. I could be wrong. Find out if the same doctors are using the same tapes; i.e., does Dr. Whatever's tape always have that problem? Do they exchange tapes around, and the problem seems to leap from doctor to doctor? I would somehow mark those tapes and keep track of them for a bit.
I have had regular music cassette tapes do the same thing, and it seems as if the treble has been completely stripped from the tape itself.
