[R-390] Sources for HP410C AC Probe

[David C. Hallam]

The article is in the June 2008 issue of Electric Radio.  It is titled 
"A Weekend Project An AC/RF Probe for the HP-410C Voltmeter".

The 410B and the 410C used the same probe.  The differences are; early 
versions of 410B used a diode with a different filament voltage so you 
have to check that and the the probe for the 410C is plug-in not hard 
wired like the 410B.
