The company is not inactive as I have communicated with Brad several times over the last month. When a disgruntled member on another forum started this nonsense I tried to correct him with no luck. He himself is the one who reported that the company was inactive when they didn't respond to his e-mails as fast as he wanted. He is the one who contacted Google. Brad responded to me in less than a half hour. Chances of finding used ones are really slim though. He is going to make a second Supratek umbilical for me when I get notice that the preamp is ready to ship.
