Whoops, of course when I was writing about tubes with red coating, I meant Z574M, not Z573M.
BTW. a random question about Burroughs tubes and their sockets, I've recently bought some broken PH meter with B-5445 tubes in it. They were sitting tight in their sockets, but after I've desoldered them, I can barely insert half of pin lenght inside sockets! Is it normal for Burroughs made sockets to require much force while inserting tubes? I'm afraid I could damage them, as I have only 4 working tubes, and these are pretty rare around the world (and non-existent in my country), so losing one would mean I lost all of them. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
