Certainly confusing to me. As far as I can see (not well note my missreading of one cap value) there needs to be a lot more wires going to the speaker/output transformer combo.
Let's see, first the field coil takes two leads, one of which will also take care of the center tap of the primary of the OPT. Two down.
Next the OPT primary will require two more leads for the ends of that winding. Two more down.
Finally, if I read the schematic right and that area has some missing lines, the OPT secondary requires 2 lines going back to the receiver for feedback and a ground. Three more lines as I can see.
That is a total of 6 lines. I'm obviously missing something here if you only have a four pin plug!
You need better help than me!
