[R-390] R-390 Non-A...have a question

[John Saxon]

Having trouble getting audio out of the local speaker connected to TB102, pin 6.

1. Discovered that pin 7 of TB102, which is shown to go to ground, has been cut.  Just a stub coming off the pin on the back of TB102, definitely cut.

2. Also see that three white wires (look like about 20 ga, but not sure) that come out of the harness that goes to the 
oven switch have been soldered together and sealed off with some shrink wrap.


These look to me like a mod (or mods) of some sort was done.  Does anybody recognize these mods?  I think 1. addresses my "no audio out of the speaker" problem.  Not sure what 2. is, may not be anything for me to be concerned about.

Any info will be greatly appreciated.
