Doing it once is bad, doing it with half a dozen is a freaking mess. See that Sangamo cap in the bottom right? There's another. I said "screw it", and started cutting zip ties and moving the jungle of wires out of the way to see what this guy was thinking.

And of course all of the components that those were attached to were relocated elsewhere.

First, the guy cut out and tested caps several at a time, then stuck them back in or replaced them by looking at the Sams, and got several values wrong, and grounded them where he felt like. But that's not the worst....

I'm redoing a bunch of the wiring to the filter can and setting everything right, when I notice something that I didn't see under a mess of wiring before. See that hole in the chassis on the far left in the second pic? That's where the horizontal size control USED TO BE!! Somehow the guy tried to wire around it and jumper connections to both the vertical size and horizontal hold control to bypass it. I have NO idea HOW this set ever worked, but I was told it did.
