Notes

Five of the nine pins are connected to the grid — when used in grounded-grid operation at high frequencies, all five grid terminals should be grounded to minimize grid-lead inductance.
In cascode amplifier configurations with two tubes in series, the heater-cathode voltage under cutoff conditions may reach 250V.
Interelectrode capacitances with external shield (RETMA 315) connected to grid: Plate-to-Cathode 0.16pF, Cgk 4.6pF (vs 4.4pF without), Cgp 2.8pF (vs 2.4pF without).
