In other happy news, I repaired my Tek 575 this evening. It had
physical damage to the step generator switch that was holding it in an
impossible mode (single-family AND repetitive sweep) and a bad 6AL5 tube
in the step generator, so the step capacitor never got discharged. It
works great now.

Congratulations!
I have a 561A that makes me happy. :-) I do need to clean its switches,
though. FWIW, I'd love to find a 3A74 plug-in for it. There's enough
stuff that I do with vintage machines, requiring not screaming hot
bandwidth but multiple inputs, that the 3A74 would just be far too cool
for words. Just sayin'?
I also have a HP 1741A that I use for faster things. At the Museum we
have Tek digital 'phosphor' scopes.
When people on this list say they don't own an oscilloscope, I wonder how
they fetch water, cook their meals and eliminate their waste products.
For folks who do what we do, a scope seems that basic, to my way of
thinking. I don't use it every day, but when I need it there's no other
tool that compares. -- Ian
