I'm pretty sure that Poly-Pak's main source of
parts was the reject bins at
DEC and DG :-). (I can't be the only one here who remember Poly-Pak, can
I?)
Remember them... I did business with them.
There was a great difference in quality in transistors then and now often
being not so much non fuctional but range of beta and leakages. I know
some are going whats that? transistors avaibale now are far more
consistant and offer far better characterestics from the days to the
2n13xx series, and the 2n35xx from years later. By current standards
those were very cruce devices and teh 2n13xx were the germainium (ft 5mhz
and leakey as hell with parameter drift with temperture that was unreal).
I know I have loads of those old parts!
