Abstract :
A conference on special electron tubes for use in electronic instruments is being sponsored by the AIEE subcommittee on electronic instruments, which is a joint subcommittee under the electronics committee and the committee on instruments and measurements. This committee, feeling that there was a need in the instrument field for tubes having special characteristics, principally longer life and closer tolerances on the important electrical characteristics, has conducted a survey of the instrument manufacturers, industrial laboratories, and others interested in a special tube program. The survey has shown that a considerable demand for such tubes exists and indicated the characteristics and tolerances which were thought desirable.
