I just tried the number Bryan gave me in Florida (figured I could ask him some questions about re-capping my Zenith, lol
)...
No luck.
He was old, he was retired, he has never written any books on TV repair.
He has no other relatives with that name.
Oh well, I guess I can say that I spoke to Art Margolis, just not "the" Art Margolis.
I still say that "Denny Margolis" is the way to go. He's probably still alive, and would put us in touch with his dad if he was around.
