content: Four-pin plastic base with tipped S-shaped envelope. Donor card reads: "Triode made by Elman B. Myers in the old Music-Master laboratories in Betzwood, Pa., during the winter of 1926-27. Given to [me] by Fred Milliken, who worked on their construction with Myers. Similar in all known respects to [catalog number 324361] and with no additional information. Like that tube, this bears some resemblance to a type 226 tube."
label: Description (Brief)
content: Card for #324361 notes: "Myers fundamental project was to make tubes for direct operation off a 110 volt power line. While the specifications of this tube are unknown, it is possible that the tube is a filamentary triode for such operation, or possible for operation at a lower voltage from an AC source, since it somewhat resembles a type 226 audio tube for low voltage AC filament operation. The use of the fine wire mesh for plates was quite common among the small tube makers at the time and of itself is not unusual for the period."
