Locus Design Group

Have they gone out of business. Internet link severed.
You mean the Lotus Group? Link was operational today. 
Cryo treated cartridges and modded vintage turntables.
I believe he passed away about 10 years ago the owner of Locus Design Group.
Dave Finley ran Locus Design - aka Cryo-Parts. I purchased some excellent pc connectors from him last summer. He shut down his retail operation this past Fall. It looks like his Linked-In page is still active. Maybe, you can get in touch with that way.
