I've got a Zenith 12H090 with the Cobra Matic changer, plays only 78's. They used what they called a Radionic Pickup that's basically just a coil of wire with a small disk that is part of the needle shaft in front of the coil. The coil is part of an oscillator circuit and the disk changes the "Q" of the coil varying the output voltage of the oscillator. When it comes out the varying voltage is detected and fed into the amplifer. I hope I've got that right. I will say that it sounds better than most of the pick ups that were used at the time. A lot of these pickups were used IIRC in Wurlitzer jukeboxes. My changer has the chain drive and it works quite well except it's pretty hard on records when it drops them. The Radio is AM and Both 42-50 and 88-108 FM. These are great sets and they can usually be bought cheap.
