There are other transistors besides 2N3904s and
2N3906s? You mean
BC109/184s, right? :-)
Yes. And 2N3055 (high current, low-ish voltage), BU508 (HV switch), BF259
(video amplifier). That's about it for bipolars :-)...

Hi
Diodes were about the same. For years it was
1N914's then the newer 1N4148 took favor.
