The 310 is close, but no cigar.

The 511 was the original Tek scope, the 511AD was a later refined model, with a distributed vertical amplifier. My working (?) 513D is probably older than Alan's 511AD. I give it a ? because although I went over it completely about 30 years ago, it has the selenium rectifiers, which tend to turn into insulators. According to Stan G's book: 511 last catalog 1952 511AD last catalog 1955 513 last catalog 1953 513D last catalog 1953 310 last catalog 1958 310A last catalod 1971 -Chuck Harris Dave Daniel wrote:
