The parts were always guaranteed. If they were bad,
you could send them back and then you could test the next
They surely created the term "You-Test-Em".

Wrong coast! Poly Paks was an East Coast outfit.
Mike Quinn's was at the Oakland, CA airport. I first saw it
in the early 1990's, I think, when it was still in the WW-II
temp building on the airport property. You were literally
walking on 3" of crunched circuit boards in the back rooms!
There were large tables covered with circuit boards and
small units, and the stuff that slid off the tables just
became the floor covering.
They had tons of boards out of computers and electronic
equipment. The best stuff was kept in front in glass cases
next to the cash register.
