Progress report, or lack thereof:
Okay, so I had three rubber-covered wires left. All three went to the front wafer of the band switch assembly.
Knowing there was no access to the terminals of the front wafer with a soldering gun or iron as the space was too tight in there, I decided to try my luck at something I have done previously, and that is to carefully peel off the old rubber insulation from each wire, and then slip on an appropriate length of heat shrink tubing.
All went as it should on the first wire, which leads from the high end of the phono input to the front switch wafer (A5).
Ditto the second wire, which is the antenna lead-in (A1).
You can already guess where this is going...after removing about 3/4 of the old rotten insulation, the third wire broke off at the switch wafer (A4).
There is no way I can see that a soldering iron can get to the terminal.
The third wire carries the phonograph signal from the band switch to the volume control circuit.
As I do not intend to ever use the phono input, I'm tempted to just leave that wire off rather than try to fight with it and and end up damaging something else. After all, these Tropic sets don't exactly grow on trees. It isn't like damaging a part in a Philco 90 as there are plenty of junk parts available for those. Not so with a 42-761.
Your thoughts, please? What would you do in a similar situation?
