Get a transistor tester and go for it .
Or at least a multimeter with a transistor test function.
haha
I have not followed the whole thread so closely - so any info about selection and pairing process will be helpful. Maybe there is more to know.
Got mıne from Frans
untıl now just the 337 measured wıth cheesy
multımeter.
All between 410 and 520.
These days ıll gıve the ıntellıgent curve tracer a try.
I have tried curve tracer (luky_z) and npn mesure fine (maybe)
PNP are way out with hfe going up to 760 which is way out of speck as 680 is max for for 40 type
This with 100% original fairchild from fairchild direct
So I am thinking that maybe sometink wrong with intelligent, not so much, curve tracer (mine at least)
Still get same nice curves and maybe to group togheter is quite handy.
But as a lab instrument is more on toy category as manual to correct error is praticaly none existant.
I am waiting for batch as suplied on Paradise parts to try and mesure those new batches and confirm that my curve tracer has ofset error on PNP.
In the mean time if Frans could post details of his set up and mesurament parameters this would be greatley apreciated
