Now I noticed that the Model 21 has an RCA Plug that says "Tuner out" was this meant to be able to have a multiplex unit hooked up to it so it could be FM Stereo like the Model 8? Also I'm missing one of the knobs on this unit and I was wondering where I might source a replacement knob for this unit.

The ua703, if made by Fairchild, looks like a slightly larger transistor. The brown button ones were extremely unreliable. IIRC, they were replaced by a GE-IC12, NLA.
