I've got a Fluke 189 DMM. The banana jack inputs are getting flaky.
With the probes or input pushed up or down they sometimes loose continuity.
I opened it up and looked at the solder joints... they look fine.
The banana jacks are encased in plastic so it's hard to see exactly.
I tried squeezing them in some, it's maybe a bit better, but no one
wants even a bit of flaky in their test gear. Any ideas? (about how I might
fix it.)

You might drop $17 for a set of ProbeMaster 8000 series leads

All gold-plated, soft silicone leads, lots of accessories available.
Gorgeous.
Even if it turns out to be the meter that's broken, you'll be glad to
have the leads for the next one!
No whatever banana I stick in there is intermittent.
(I use a lot of BNC to dual banana plug adapters.. then I can watch
the fast stuff on the 'scope at the same time.)
Ah. Those put a lot of torque on the solder joints, of course.
