My deepest condolences to Mr. Van Alstine's family and friends. I did not meet him, but have been a follower of the company for many years, aspired to own many products, and when I did, always enjoyed them. His openness and generosity, in Audio Basics and especially this forum, was nearly unique in this industry. His support of older, second-hand, and discontinued products was an example of this generosity.
I hope that the memories of those close to him will keep him alive in your minds and hearts, and will be a comfort in this difficult time.
