I'm curious as to your experiences with tubes in long term storage. The question is, which type holds a vacuum better - glass or ceramic, or is there no difference? My own limited experience says ceramic is better, but that is only with a few tubes. All comments welcome. 73, Bill W6WRT _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
