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
