It didn't occur to me at the time (almost forty years ago), but with so very many junk parts coming in, I now wonder if those incoming parts were counterfeit? I guess I'll never know.

thanks again for another Interesting article. "When I was a boy", I built a UA709 hybrid with the frequency compensation circuitry in a TO-8 package in the early 1970's for General Instrument. I never knew how much of a problem it was to tame the op-amp until reading your blog.

The problems you saw in the early 1960's with semiconducors were before the mil-specs, ISO9000, etc. were written and when "garage semiconductor operation" could advertise they had an equivalent part without an liability or they re-branded scrap material which was very common on transistors and diodes.

The counterfeiting today is more of an outrageous fraud as seen on "60 minutes" and is currently under congressional legislation
and certifications for distributors.........
I saw Senator Carl Levin & McCain grilling several government contractors and top DOD officials this week including

Those guys in Ohio buy millions of $ in electronic spare parts every day in auctions for Military use with central purchasing in Ohio, ought to know better. But then there are so many shlockers in that biz, Certificates of Genuine Origin are printed on toilet paper then photoshopped onto original letterhead and printed . ha
