I think the golden cheroot goes to Charlie......flybacks seem to be pretty notorious on both Zeniths and RCAs.....at least in my experience. My hearing had big chunks of missing frequencies but I do hear some that are outside of the normal higher range due to a fused bone structure (or sumpthin like that).....anywho, I can actually hear some ultrasonic motion detectors in alarm systems. Because of this I drove RCA crazy with a new set I bought in the early 80's as it wouldn't stop squealing no matter how many flybacks they changed under warranty.

One repair shop thought they would put ME to the test and see if I was just a crack pot.....with the set on the bench and me just outside of the door so that I couldn't see it they'd ask me when I could hear it as they turned it on and off......of course they tried to fool me a couple of times but I nailed it 100% Shut them the hell up! And then there was the time I almost passed out from all the motion detectors in the Gold room at the old San Francisco Mint. Walked thru the doorway and nearly hit the floor from the instant dizziness that overwhelmed me. Shoulda sued da bums.
