I used to use one at work (in the early 80s). I could probably still
run it, blindfolded.
Your challenge will be to KEEP it running. Even the newest of these
is well over 20 years old. They drift, a lot, and lose lock. You'd
be better off with a 7L13/7L14 ... and don't forget the matching
tracking generator, which goes in an external 500-series instrument
frame.
A 7603 scope box works great for the 7L series of analyzers. Speed
isn't critical as the analyzer's not an oscilloscope. The display
isn't all that high bandwidth.
Don't get the phosphor-memory screen version, too easy to damage, and
besides TOTALLY unfixable even if you DID find a working model.
Just be careful what you buy. When one of these dies, it's dead, and
that's the end of it. Not really repairable at any reasonable cost
compared to the replacement value.
Karin K3UU (a former manager of mine) is the only person I know who
still has a 7L12 these days. You can ask her what she thinks. Don't
have contact info handy.
