Allrighty, getting into some meat and potatoes here

The attached pics show the restoration process so far, set belongs to a guy in Maryland. This thing had a filter cap bigger than anything I'd ever seen before, it was the size of half a stick of dynamite !

Decided that the best way to replace the two monster caps was to mount a PC board underneath with stand offs and hot glue. Worked out very well, as you can see . I absolutely HATE to leave filter caps dangling underneath a chassis. To me, it's both sloppy and unsafe. Of course, there are times when that's all you can do, but there was enough room to mount everything there, so why not do it right

Here's where I'm at right now, and a couple questions. I should preface this by saying that this set is in Sams 389-4 (which I don't have). I realize that some of this could be answered if I HAD the Sams, but I'll give it a shot anyway, just in case someone knows, or happens to have it.

1. In the second picture at the bottom right, note that white thing has been subjected to a tremendous amount of heat.....so much so that it burned off the contact on the junction strip. I assume that's a ceramic resistor of some sort. What is it, and what kind of failure could have caused that much heat?!?!?

2. Same picture, far upper right, there is a dangling wire lead that goes nowhere.....

3. I'm going to need help with this one identifying what I need to do to replace the selenium rectifiers. First time I've done this.....
