Von schweikert out of business since Albert's passing?

I have tried and tried to contact Von schweikert via email and phone. I call numbers listed in my manual and they are no longer in service. I have left messages on other numbers that ring. Funny thing is years ago when I emailed Von schweikert he himself answered my questions and made an amp suggestion for me. Has anybody had recent contact with them or know the status or the magical phone number that gets answered?
