Russian 10Zh12S / 10Z12S indirectly heated high-frequency pentode, octal eight-pin base for long-distance wire communication voltage amplification. Nominal heater approximately 10 V, 320 mA (source 10±1 V), maximum plate voltage 250 V, screen voltage 180 V, plate dissipation 1.9 W, screen dissipation 0.4 W. Typical transconductance 1.85 mA/V with manufacturer tolerance ~0.25 mA/V; previous mu=10 is unsupported and cleared. Manufacturer guarantees 1000 h service and gives −60 to +70 °C ambient range; distinguish measured operating from limiting values.
