LOL... I have the chassis back out of the cabinet, and am going to replace Z404 with a replica I made by wrapping paper around a .01 cap to which I soldered, close to the body, a piece of #24 stranded insulated wire. I wrapped the cap with paper to increase the diameter and length to approximate that of the original .01 paper cap. I had measured the wire to approximate the length of one leg of a TV rabbit ear, which seems to be about the length of the wire wrapped on the original, if not a bit more. We'll see if this makes a difference. I am also going to replace a number of resistors that set various voltages in the power supply and the bias voltage dividers for the FM section. I really think the set can perform better on FM than it is now. I am going to wait to start the work until I have all the resistors in before I begin again. We shall see.
