Traian makes a very good point. Some 35 years ago now, I was at a company
doing MF SSB maritime transceivers. The Buyer was instructed to buy the
cheapest transistors, and bought from Microelectronics in Hong Kong. First
problem was low drive - the 2N3866's were below JEDEC spec on DC Beta, and
we didn't bother trying to measure Ft. The reliability of the BC108's was
terrible - they didn't meet the published specification on Vcbo.
And of course, it was all the fault of Engineering!!!!
Somehow, this sounds a bit reminiscent of the horror stories of the early
3-500Zs from the far east.....
