*Richard* - What are the date-codes on your tubes ? I recall hearing problems with IN-18 tubes manufactured in 1982 (82xx date-code).
I have one from 1977, another from 1986, and the rest are from 1989/1991 -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
