I am about to get started on LM399A volt reference journey with the calibration club.
The plan is to have a couple of reference boards finished/aged in boxes to compare against each other and other peoples references once they stabilise.
And maybe one day when I have at least a bit of practical experience with the 399A circuits, I'd also like to do something with an LTZ1000 because that's the big one, and why not go all the way?
One thing I'd like to try, would be to get myself some machined pin sockets so the 399s can be attached/detached and swapped between reference boards without soldering. But I'm a little leery of what could happen here with the connection possibly not being as solid as a soldered one, and surfaces oxidising over time.
Has anyone tried this before?
