Hi, Peter (and Bill and others),
I owe you all some information, which I will get to this weekend. I
apologize - I have been out of country for work related reasons, and have
been away from my workstation, for much of the past few months. Finally, I
have returned home. Be in touch soon.

I've done a bit more digging in the literature on this topic, and found
basis for an operating life exceeding 100K hours for the ETL low speed
tubes if all the various pieces of advice on how to keep the tubes happy
are followed. End of
