[R-390] HP-410Bs and AN/URM-25s

[rbethman]

Ashley Hall, HMIC, (Head Mother In Charge), <Kiss-Electronics.com>,   no 
longer refurb or support the AN/URM-25s.

However, She provided me with a parts list for what the used to do.  She 
also provided me *Their* procedure for refurbishing.

I can provide this to any and all that desire this.  (If enough want 
this info, I'll put it on my site for download.)

She and her crew are providing the equivalent services for HP-410s.

I recently procured a DC probe for mine.  My HP-410B is a peculiar one.  
My probes are NOT soldered in under the chin.  Either a previous owner 
built a beautiful aluminum piece with banana jacks for ohms and common, 
and 1/4" Phone jacks for the DC and AC probes, OR it is a prototype.

I don't know which, but it was done in a very professional manner.

It makes thing a lot neater on the bench, as when not in use, the meter 
can sit on a shelf, and all the probes can be hung up out of the way.

I've checked the HP-410B against known, 1% resistors, known DC source of 
3.7VDC, and checked the AC by a known fixed voltage.

The old gal is right up to snuff!
