Shoutout to the old Fluke 87V for a weird autopilot fault find

I was chasing a phantom voltage drop on a Citation's pitch trim circuit last week, and my newer meter showed nothing. Grabbed an 87V from the back of the shop, and it caught a 0.3VAC ripple the other meter missed. Anyone else have a go-to piece of older test gear that still finds stuff the new stuff doesn't?

Remember my buddy's old Simpson 260? @theac63, it found a ghost ground.

That 0.3VAC ripple is a sneaky find. What kind of newer meter were you using that missed it, a true-RMS one or something else? It's wild how some older gear just has a different feel for noise.
