Abstract:

JAN-5703WA- Varying filament voltage had greatest effect on pulse current characteristics. Envelope temperature and plate dissipation had a lesser effect. JAN-5896-Filament voltage was the only cause of pulse characteristics changes. Percent operatives were excellent under all test conditions. JAN-5902-Pulse characteristics were very stable. Early hour stability was affected by variation of filament voltage. Envelope temperature was of great importance in causing catastrophic failures. Filament voltage ranked next by a factor or 3 to 1. JAN-6021- Filament voltage was again the most important factor with envelope temperature and plate dissipation of less importance. Type 6286-Mechanical Excitation-Percent operatives of lower G lots were slightly better with voltages applied. No difference was noted between operating and non-operating lots. Lots with higher G levels developed more vibrational output voltage with time. pulse life test mechanics and general tube performance are discussed. Author
