2n1921 matched pairs


2010-12-24 2:15 am
hi - I have quite a few 2N1921 transistors packaged as matched pairs. They were given to me by an older friend (fellow ham radio operator) who was working on a rather challenging audio project.

I wondered why matched pairs were so important. Also wonder if the "matched pairs" are useful to anyone - or has their usefulness gone away with the passing of time. Also have some RCA transistors - 40310, 40319. Hate throwing the stuff away. Hate using in place of cheap common stuff. Would like to get to someone who could really use this stuff.

Sorry for the babble
