Philco Tropic 39-770EZ
#56

Well, let's get back to the subject at hand.

There was one coil that looked suspicious - the first SW band (band C) RF coil. It has good continuity, but the wires had obviously been removed and resoldered at some point. In addition, one of the wire leads had a resistor and another wire soldered to it, with no support. Not a good thing.

Here is how it looked initially. I needed to lengthen the wire leads and add insulation to each lead.

I took some wire from some leftover AC cord, which is very thin strand. I used five of the strands from a length of that wire and made a stranded wire with which to lengthen one of the coil leads.

Here, you see the first of the four leads has been lengthened in this manner.

Now, three of the four leads have been lengthened, and insulation added. The blobs of hot glue were placed to help hold the wire leads in place and was done in an effort to keep the leads from possibly breaking off at the coil.

I needed an insulated terminal, which was anchored in place to something solid, to hold the fourth wire lead as well as to use as a tie point for that lead, one end of 5K resistor (16) and a wire going to terminal B7 on the band switch.

Fortunately, the shield between the antenna coils and the RF coils was removable, and there was enough room for a small terminal strip on it at the point where it was needed. So I drilled a hole and attached the terminal strip you see here with a small steel pop rivet.

Now, the rewiring and reattaching leads of coil (8) is complete. Icon_smile
