After much research I found a reasonable source for D5 here in Canada and they will ship to the U.S.A. You may find the info at the top of my blog page at the moment. www.richardhess.com/notes or go directly there http://richardhess.com/notes/2012/10/09/source-for-d5-decamethylcyclopentasiloxane/ I know I have been discussing this off-list with a few of you. There is also another blog post a couple of articles down about it working very well with Sony PR-150 on a Sony APR-5003 recorder with a simplified applicator using an envelope moistener found at many major stationary suppliers. http://richardhess.com/notes/2012/10/01/playing-a-squealing-reel-of-sony-pr-150-tape-using-d5/ And, for something completely different, I have updated my article about my personal image scanning work, celebrating the completion of the bulk of it. http://richardhess.com/notes/2011/11/05/personal-image-scanning-project/ but all three of these are currently the top three articles on the blog (on my blog they sort by last-edited date so updated articles are recycled on the main page).
