[time-nuts] HP 3586B Selective Level Meter...

[Burt I. Weiner]

I've seen severe damage to the motherboard caused by the battery 
leaking onto it.  I've bought two with all the options from eBay, but 
will not consider one unless they seller shows it up and running, 
even with errors displayed.  If I see it's running almost all other 
problems are fixable.  When I do get one the first thing I do is get 
the battery out of it.  So far I've been lucky.

I've replaced the WECO connector with BNC connectors for the WB input 
on all of my HP-3586B instruments.  I replace the battery with a 
cordless telephone 2.4 Volt Nicad jobby and mount it on the back 
panel by extending the leads from the power supply board.

Are any of you familiar with the Beethoven test?  This alone makes 
the price of the instrument worth it.
