I've ordered the 0515-1245 from Keysight directly (see
). You'll need an
account on their parts store. FYI they're not cheap: like $4 each (when
I bought them), so 100 is going to cost you. Also, they're torx, not
pozidriv.

Unfortunately, the 0570-1171 appears to be obsolete. But, if you can
find another part number that might work. Or, you can reach out to
Keysight and they may be able to tell you a compatible replacement. If
you find that out, please report back! I'd be interested in that as
well.

The retaining rings are also orderable (eg 0510-0043), but typically you
can just reuse the retaining ring from the existing screw.

There's two (one is for the short assemblies and has RF connectors for the A8 module), and I'm not sure I can point out which one's which, but per SM:?

They offered a large stock of extenders for common pitches/widths.? I bought a bunch and used some as-is, others I modified or cut down to suit particular instruments.? Gave me a very useful result.

You can use the vinegar/salt/hydrogen peroxide to etch them at home

if you can use some kind of resist (toner transfer, UV film, sharpie,

paint, etc).

Just file a slight bevel on the fingers for easier insertion.

Lots of free CAD systems for PCBs out there including web based if you

want to send it out to a board house for something more professional

I had a script for gEDA to generate edge connector footprints.

Should probably dig that out; I need an extender card for an 8754A.

Hi Jeremy, thanks for the response and the info. I didn't know HP did that in the manufacture of these? meters. This one is an early 410C that was decommissioned out of Norden. It had been stored where frequent temperature changes occurred where the magnet assembly on the meter movement had moisture accumulate at the bottom of it. The rust was thick enough to halt meter movement at say 10 volts and beyond on the 15 volt position. Opened it up and was able to clean out enough rust in the gap to get the travel to full scale, but still gets sticky in that 10 to 15 volt area. So far I have only improved the situation and done no harm to the movement. At this point I will press my luck and open it again. Last time I used small cut pieces of a business card lightly soaked in alcohol. I think this time I will try those small plastic dental picks with the small brush feature and see how that works.
