Roger Russell's site is nice...but he 's hardly impartial. And I
would say that more of the extant chrome chassis tube era Macs in
excellent to mint condition are in Japan than here today-ones coming on
to the US market tend to be cosmetically bad, modified, or detectably
reworked, replated, et al. Especially the 275 which is the John Holmes
model.

I don't mean to disrespect Roger, but, he was the speaker guy and the
speakers Mac has built did and do not have the reputation that the
electronics do.

And the electronics-look inside a modern Mac product and then inside a
Tek oscilloscope from the 50s up through the end of the
in-house-made-CRT models. True, most other High End audio fails this
test as well, but for this much money, that's my expectation.

You can't compare any piece of audio gear to a Tek scope.
As "R" remarks, Tektronix scopes, especially the 500, 600 and 7000 series,
were built like nothing else on this planet.
They are singular examples of design quality.
