Nice work. A crude test on the caps is grab them by
the leads with needle noses & pull. They usually
come apart. Triplers cracked open left & right on
most sets back then. RCA seemed to have the least problem.
I remember now 977-36 was the latest # for this tripler.
Used to get them by the dozen from Zenith for $10
each, almost as good a profit as tubes.......
