Those folks did really neat stuff. The ceramic strips in your old
545A were Tek-made. They kept the stray C down. The vertical amps
were designed to be flatter than a plate of piss. This was done by
using lots of low gain stages. There was one 500 series box that had
7 pairs of 6DJ8's cascaded in the vertical amp. They also made
their own crt's, as no one else was accurate enough.
There were a couple of Cybers, I'm thinking a 75 and a 170, but it's
been a while. There was also rumored to be an electron beam geometry
modeling program that they weren't allowed to run during the day.
It apparently brought the 170 to a crawl.
Seems some marketing types had bought into the same marketing crap
that NCR/HP/whoever did AFA cabinet colors. They developed a line
of "Earth Tone" colors. These got prototyped. Not long thereafter,
Howard Vollum ($FOUNDER) ran across these. His only comment was
"Tek scopes are blue". Brown went away.
It was a really neat outfit to work for. Sometime in the early 80's
(I don't remember exactly when) Howard went face down in his plate at
a Portland restaurant. His successors didn't have his vision, and
the rest is pretty much history. Tek is still around, but it's
much more marketing driven. I really miss the days when it wasn't.
