Promoted ratings/characteristics from HY113.pdf. Hytron HY113 Bantam Junior directly heated 1.4 V, 70 mA low-power battery triode for RF oscillator or detector service. Typical test point: plate 45 V, control grid -4.5 V and plate current 0.4 mA. Published intrinsic amplification factor 6.3, transconductance 250 µS and plate resistance 25000 Ω. The 45 V plate condition is typical, not an explicitly declared absolute maximum.
