RE: Is this available?

That's because the product is in beta trials now. John is one of my longtime beta testers and couldn't restrain himself once he finished it and listened...

This product originated several years ago as an idea (and a first prototype) when I was negotiating to bring Rauna/Opus3 turntables into the U.S. and sell them. Ultimately, that didn't work out, so the TT PS languished. One of the guys here in Audio Sunday School (Trent) helped me improve the design by building variants that we could test. The current design emerged from that effort. Several of the guys here built them in 2010 and nothing more happened due to my time constraints.

However, contacts who reacted to my webpage get trickling in and John pestered me for 3 years to get him one. So I relented and made minor PC board changes, and now plan on getting a small batch out there available to purchase. I haven't taken any pictures except the one attached. Due to the time necessary to support a kit, I'm strongly considering offering it assembled-only. The price will be determined in a couple of weeks, but it will be between $700-$1K. The features that my supply has are very similar to ones that high-end turntable manufacturers sell for $2K-$4K. Compare the features that John describes to the more modestly priced ones offered by, for example, the Music Hall Cruise Control (http://musichallaudio.com/cruise-control/) or the VPI SDS Synchronous Drive System (http://www.musicdirect.com/p-7709-vpi-sds-synchronous-drive-system.aspx). Both of these have impressive frequency displays that are really good only for noting the correct frequency for old off-pitch 78s! I've put the money behind features that LP players can use to improve their music listening.
