One of the wires had broken off the audio transformer, the remaining were not looking good.
Carefully took the transformer apart to solder intermediate 30 gauge wires onto the tiny input side windings, these wires are in turn soldered to the larger wires that exit the transformer.

I used friction tape to wrap the transformer, it can be locked in place by applying cyanoacrylate to the tape ends. Once installed onto the chassis it is soldered in place on it's folding tabs.
There are only 3 wires on the audio transformer because one side of output is tied to chassis ground. The speaker plug will return speaker current back to chassis ground at the speaker plug.

While soldering big stuff with the propane torch I also installed the triple electrolytic capacitor.
The capacitor body is the common terminal of the electrolytic. At lease one mounting tab must be soldered to the chassis to ensure a good connection to ground. I often use tinfoil as a heat shield when soldering this way, the torch will quickly burn things or cause discolorations if not contained.

The power transformer also gets one edge soldered to the main chassis. The center tap of the input side of the power transformer is tied to chassis ground internally; this soldering is necessary to ensure the best performance from the power stage.
