Voltage - Triode (single) ·Triode
Directly heated Standard Valves triode; the E version uses a filament designed to reduce sputter noise, while the G variant improves grid-to-anode insulation.
Directly heated triode. The 4101-D, -E, -G valves have similar characteristics. The 4101-E valve has the filament designed to reduce sputter noise. The 4101-G is similar to 4101-E but has the anode lead brought out through the stem to increase the grid-anode i
