Re: Type G plugin versions

Further study of the catalogs suggests that they never did retool. In 1967, some instruments with plastic trim went "limited demand" without pictures; others simply dropped the trim. As far as I can tell, the hole stayed the same size. It's possible that the BNC was switched from square four-screw mount to round flange and single large rear retention nut. If I remember to, I will study my plugins when I'm at home this weekend.

Wow- my G is s/s 9934, so it's just after the change. Strange that they didn't change the sheet metal right away.

According to the later manual Type G switched from UHF (131-012) to BNC (131-277) at S/N 9480. No idea in which year that was.

I don't know the G serial number at which Tek switched from UHF to BNC*, but
the 1962 catalog shows UHF while 1963 is BNC**. I think I have a newer manual
at home, I'll try to remember to look.

There was a mod kit for converting instruments in the field. I have at least
one modded scope and plugin. Yours too, most likely, as Tek would not have
sold instruments with such an obvious bodge.
