Dean was in charge of designing the 453A, the best scope Tek ever
made (I have 3 of them).

Then you've never owned a 485, my personal favorite.

That was the *huge* dual beam one, yes? With the separate
power supply?

Nope -- that was the 575 IIRC. The 400 series were all nice
compact little scopes.

Those things were pigs, hard to move around at all.

The 575 certainly qualifies for that. I turned down one *free*,
because I knew what I would be getting into. :-)

I got my start in an electronics shop, renovating RM45s.

As already mentioned on this ng, I found out that you should
never ever ever ever try to remove the graticle from the
front of an RM45's CRT!! Boss caught me in the store room,
trying to pry one off with a screwdriver. "What the *hell*
are you doing??"

"This damn thing's really stuck on here...."

As in bonded to the CRT. Get it loose, and you let the vacuum
out. :-)

The 454 at least had a coil around the neck of the tube to add a
magnetic field to rotate the trace into alignment. Adjustable by a
screwdriver from outside the scope -- in the little accessory connector
panel on the right side, IIRC. That panel would hinge out to parallel
the scope face when the scope was in the rack-mount shell, so it was all
accessible from the front.

Enjoy,
DoN.
