These are rare as hens teeth… My uncle Dr. Sao Win of WinLabs.
Grew up carrying crap up to CES in Chicago for my uncle for big audio shows. First time I held one of his turntables I was shitting tacks.
During the show he would close the lid and then hit the damn thing while playing with his shoe.
He made the turntable, the strain gauge phono cartridge, the magnetically levitated tonearm and the preamp for the cartridge. That was a big part of my childhood.
Thank you God for music!
