I finally finished off this Tandem tonight. It's been playing a couple hours with no problems
I've tried a variety of products to clean the cable and so far denatured alcohol works the best.
This is the head unit with a rebuilt 21EVP4. Eventually I'll get around to restoring the head that came with this set originally.
The rebuilt picture tube is very bright and I had a hard time taking a decent photo.
Although the cable is 25 feet long, I suspect most CRTs ended up on top of the cabinet.
Here's a shot where the geometry defects are apparent on the right side. I think careful placement of a couple small magnets could improve the situation.
