just a quick note...
I have been using 2 different data sheet guides for a while:
http://www.datasheetcatalog.com/
http://www.alldatasheet.com/
...but both don't seem to hold a candle [for old transistors] to this Russian one I started using recently:
http://transistor-spravochnik.ru/
for instance, just today I looked up:
TR09, 2n223, 2n43a, 2n1149, 2n1154, 2N389
The only one that had info on any of those was:
http://transistor-spravochnik.ru/
btw, I did a search on this forum ["transistor-spravochnik.ru"] and it doesn't seem like the site was mentioned before.
