Hi Jim et al,
Nick and others have pointed to various references to Beacon
326. I'm a little disappointed that I didn't find them myself,
since I've been a bit of a bookworm on Teletype docs.
Unfortunately google hasn't found anything less than a bucket. I just want a tube or 1lb tub.
I suspect if I study it further I will find that something is close enough. After all most of us don't run these machine 24/7.
Need to contact my brother who is a certified aircraft mechanic,
although I'm not sure how much he knows about delicate instruments
(referenced as an application for Beacon 325) with everything
going electronic.
