It's a 2N3866, not a 2N3566, from what I could see. The 3866 a 1W
800MHz ft device, which makes much more sense for a 50MHz sig gen.
It's also used as the vertical deflection drivers in the 100MHz Tek
465/465B, among other models.

If what I could see of Rico¡¯s reply, 2N3566 transistor, is correct
then here is the info for that transistor. The comment also
indicated that it was a selected transistor. My best guess since
you indicated it was a 50MHz generator is that it was selected for
50 MHz operation vs. the 40MHz spec. on the 2N3566.
