Was suggested by a member in PM a while ago (honestly don't recall who) that suggested that I look at the yoke for the problem. Bought a new yoke for the set, and it's sat since about 2 weeks after my last post on this.
Now that I've got a yoke tester and have learned how to use it (very easy BTW), I tested both the new yoke and the old. Looks like that's (at least some of) the issue.
Here's where I'm at. Aftermarket yokes always make me scratch my head, but with the supplied diagrams usually I can figure it out. This one's confusing me a bit.
Below are the pics of both the new and the old yokes. The old yoke has colors red, red/black, green, and tan/black. The new yoke's wiring is green, green/black, tan, and tan/black.
As well the new yoke has caps in it while the old doesn't. Resistors are the same.
Appreciate a little advice
