alternative power supply for Garrard 301

Can someone share detailed info about what the Mark Kelly power supply unit "features" are? I'd be interested in an upgraded power supply as well and if possible to get in on the original group buy since the initial batch hasn't been delivered yet. Glad to hear the designer's health is improved!

Palasr, The price list won't come up on my computer, perhaps it's due to my using a Mac with Safari.

Jcote, none of us knows any details about Mark's design, much less its features. The project dates to the origin of this thread, about 2 years and 4 months.

Wow! I misspoke. I totally forgot about this page (see URL) which does describe some specs and features for the Kelly Motor Controller:

As you can see, the date is June, 2011. I know that Mark is a perfectionist and makes changes as he sees fit, so this should be taken as a ballpark idea.

Hold it. That seems to be a page I bookmarked long ago on the hope that it had something to do with Mark's work. But looking at the spec sheet, I think it is a product from another "Kelly". No way our MC will need to deliver "100A".

Have any try the sound-carrier from croatia as suggested by Gilles130. There is another 1 from space-tech-lab fr Canada which is frequency & voltage adjustable at not so cheap price of C1280. Martin bastin sinosaur for GBP600 and another 1 from Uk called pure cycle http://www.britishaudio.co.uk/benduncan.html for GBP399. More than 2 years of waiting to listen to my refurbished garrard 301 with reed 2p (pernambuco arm wand) & ortofon A90, I m running out of patience & will probably buy a local DIY unit or 1 of this unit or maybe loricraft 401psu while waiting for mark Kelly unit to be develop.
Any input from anyone who has other alternative is welcome
