[time-nuts] Re: A Nice Slice of History

The Link worked fine for me, thanks Nigel, just took a while for all those pages.

On Page 232 there is information on crystals with two sets of electrodes, common on the low frequency bar crystals that I have quite a few of, and a few others on this list have a few stashed away.

The following couple of pages are quite interesting and give yet another link to a free book for more information - "Electromechanical Transducers and Wave Filters" from 1942 which give more information.

The book -

Takes even longer to download because it's coming from The Archive.

Enjoy, and Merry Christmas too.
