I would like to find the models of the 2sc1913 / 2sa913 and 2sd424 / 2sb554 bipolar devices, but it seems to be impossible, no results with Google
Any source?
Many thanks in advance
Max
Yes I know they are very old models but they have often been used in famous amplifiers and so I tried and do a search here.
Unfortunately I'm not able to make models, maybe someone more capable than the forum could help me. Thanks in advance Max.
