Nice work! Persistence sometimes pays off and yes, people can do strange things sometimes. This reminded me of a radio I was given 20+ years ago. It had been my great-uncle's and he had taken it to a radio repair shop decades before (a Crosley Mohawk) and when it came back it didn't work, so he put it away and ignored it rather than go back. I spent hours .... many hours trying to find out why the voltages wouldn't measure correctly even though ALL the parts were in their correct places and in good shape.

Turns out some *$%#@ had clipped out the wire that was the B- return ........ it just wasn't there .... period. I wired it in and that radio played like a champ!

Good for you !
