Hi you-all. I would like to mention again that I work at 
kurz-kasch...One of the worlds oldest plastics manufacturing plants 
in the world..We been getin-r-done since 1916. We still manufacture 
some tube sockets and have others in stock..I am no expert on what 
fits what tube but, with a little help, I might be able to dig a tube 
socket or 2 up.....let me know...Chip
