I had read awhile back that Andy was planning to retire. However I have no knowledge though that he has actually done so.
That being said I was unable to reach him once either for quite awhile. I wanted to order some tubes. When I finally did talk to him he said he had been away on a west coast trip to buy tubes. He had spent quite a bit of time at some Hewlett Packard plants I believe. So not unusual for him to be out of touch for over a week. Other times it took a few days to reach him. I would recommend to keep trying to reach him for now.
