Hi
Working on this radio and wondering about the purpose of a 3 pin connector on back of chassis.
It appears to accept a mating connector of 3 straight pins. On the schematic if you were to look
just beneath the loop antenna connector you will see what I'm referring to. Looks like one pin
is ground, one goes to one of the leads from the loop antenna and the third to the antenna coil
on the chassis.
I'm guessing this is for a "long wire" type external antenna. Would this be used for both SW and
AM broadcast benefit? Is the built in loop also for both SW and AM? Would you just attach an
insulated lead wire to the upper pin and run the wire inside or outside for improved signal?

This unit has the record player built in as well. Things have been missing so not clear on how some
of this stuff was connected. Now on the chassis back is another connector that looks like the type
used in car radio antennas years ago. This must be the audio input from the phono. On a wooden
brace in back of cabinet there is a terminal board. On one end there is an "RCA" type connector which
must be the phono output to the radio/amp. So... one end uses the "car radio antenna" connector and the
other the RCA type. Could one just take some two conductor shielded cable and make up the cable
with appropriate connectors? Also that terminal strip has two screw terminals which must accept the
loose wires from the chassis which I have traced to (1) ground and (2) to the rotor of band switch.
If I'm reading it correctly, this switches in a part of the "OSC" coil when in Phono posistion but I'm
not clear of the purpose. Could someone help on these questions?

One more... where would you suggest I get the speaker re-coned? (12 inch)

Thanks very much!
