Was about to install the can back, but one of the screws would not tighten. It developed some mushed therad. Would noty come out and would not tighten.
I tried bunch of tricks: pushing from the top while unscrewing, pulling with pliers and unscrewing, prying with a flat screwdriver while unscrewing, even tried the cat's claw nail pulling tool....nope.
Eventually I took my Dremel, cut off the tail, then cut off the head, then used a punch and it came out after an hour of flipping the bird at me.
A spare Philco screw went in just fine.
Will reconnect tomorrow.
Then the electrolytics.
