check out also this:
FS: 15 pcs. Genuine Toshiba 2N3055

I am looking for an opened 2N3055 pic, first time launch from RCA between 1963 and 1968 so as the first RCA advertisement about the 2N3055 for the thread
2N3055 inside - commercial famous amplifier models, quasi complementary power output

BTW - who was the developer of the 2N3773? First release from RCA or Motorola?
