Nic, many times volt-nut questions are posted here, including by me, and no one has ever said "get outta here, we're TIME-NUTS."

I currently have two 732As, a Fluke 5440B, a couple of Datron 1082s, and not too long ago got an HP3458A and had it cal'd by HP in Loveland. One thing I've discovered so far about the 732As is that you really only need one unless you're a belt-and-suspender kind of guy. Either of mine reliably return to better than 0.1ppm of base from several cold starts, given a warm-up of a day or so, so I've dispensed with the batteries completely. Over the last few months, the two 732s track within 0.05ppm as measured by the 3458, which also tells me that the 3458 is pretty good too. 

I know of no other "volt-nut" sites, but others here may know of some -- I hope they do. I do have a web site of my own, but I haven't yet set up a volt-nut blog -- I'm looking at the Phorum open-source software for another project, and if I think the traffic won't be real high (how could it?) then I'll look into the possibility of hosting such a thing. In the mean time, Volt On!!
