The photos are a bit fuzzy, so it's kinda hard to tell. The small transformer at the top of the chassis is your audio output transformer and two wires should go to the speakers.

Picture #3... cant really tell a whole lot.

Picture #4... that's your antenna connections. Two of those leads should go to the tuner. Also, that big shiny piece of foil paper in the top of the cabinet is your "built in" antenna. If you are using an external antenna, the leads going to the foil paper thing would stay disconnected. There should also be attenuator switch nearby for that internal antenna.

Can't tell much about that single wire by iteself.

The socket you see to the right of my antenna board is for the optional wired remote. The wires that go from that socket travel down to another socket behind the 5U4 tube (which looks empty on your set) and also goes to the tuner motor.

If you like, PM me with an email address, and I'll send you a much larger photo with better detail of the inside of my set... and maybe you can match up some of what's in your set.
