[time-nuts] Finding precision resistors, tip

[Brian Kirby]

One of my methods of finding precision resistors and parts is looking at 
old test equipment at hamfest.

An Fluke differential voltmeter, usually has a Kelvin-Varley precision 
divider assembly in it that is made out of precision resistors.  If the 
instrument is inop, its usually very cheap to acquire and a great 
salvage candidate.  Why your at it, salvage the reference diodes and 
note there is usually some markings near them that denoted the current  
that was applied to the diodes, and sometimes the reference voltage.
