I'm about an hour away from Mendel-junks. Their building takes up a city block and is about 6 stories high. Only the thirdd floor is open to the pulic. The third floor has tons and tons of junk and old, old components. I bought about 4000 silpads there a few years ago and found some exact switches for early 700B's. They had a lot of germanium transistors for the V/I limiter circuits. I've also bought wire there. I hope they're not shutting down as I usually make a trip there once a year.
