Anyone know what happened to Welborne Labs?

I worked with Ron Welborne back in the 80s at Honeywell Defense Avionics. I knew him pretty well and was surprised to see that people had paid for items and never received them and looks like his website is gone. He had a son Daniel and I thought he might have taken it over. Anyone know?
 
I had some direct dealings with him as a customer, nice guy, waaaay smarter than most. Dealing with the clientele I deal with at my current job, I think he was dealing with things that got on top of him and that hurt the business. Not saying that to slam the guy, I really liked him, even though he owes me 40' of DH Labs 18 ga......And we are all still waiting for him to make a 300B pp amp.....
