So, what's your (or anyone else's, for that matter) opinion on the Tek
465B? I bought a used one as a Christmas gift for my partner; with two
probes, an original manual, and shipping, it was around $600. It
appears to work fine except that when I connect the probes to the
square-wave calibration output, the horizontal portions of the waves
seem to be much "thicker" vertically than they should be. The vertical
portions appear to be reasonably sharp, however. I've tried turning
down the intensity and twiddling the focus and astigmatism adjustments,
but it's not as sharp as I would like to see. I can probably trade it
for another one, but it means more shipping and possibly late for Xmas.
Anyone know if there's another adjustment I'm missing? I've only got
the user's guide - not the service manual.

One thing. A good second-hand scope (like a Tektronix or an HP) will cost
about the same as a new low-end unit. There is no comparison in the
quality, though - the Tek/HP is the much better instrument. And it's
probably more reliable as well. I have had plenty of problems with some
makes which have horrible triggering, non-linear timebase, etc.
