[sdiy] Ge transistor tester weird results

[Michael E Caloroso]

Ge devices are notorious for reverse bias breakdown.  That would confuse
any auto detection test algorithm.  The only bench test equipment that
would work for these is a curve tracer.

I would never trust any NOS Ge devices on the market.  By now the supply
will have gone through multiple hands, with good ones retained and flaky
ones passed to unsuspecting buyers.
