The dual-gate construction reduces the internal capacitance between the drain and the input gate, which improves stability and prevents unwanted oscillations at high frequencies. Typical Pinout (TO-72 Style) VGS(off)cap V sub cap G cap S open

The "dual-gate" design is the defining feature of the 3SK41, allowing it to excel in two specific areas: The datasheet for the 3SK41 reveals the solution:

The 3SK41 stands out for its balance of speed and thermal stability:

Standard transistors were prone to oscillation and cross-modulation, essentially creating interference that ruined the picture. The datasheet for the 3SK41 reveals the solution: a device with two control gates instead of one. By inspecting the pin configuration and electrical characteristics in the document, we see a device designed for "Automatic Gain Control" (AGC). The first gate accepted the weak signal from the antenna, while the second gate controlled the amplification factor. This allowed the TV to maintain a clear picture whether the signal was booming from a nearby tower or faint from a distant transmitter. The datasheet’s curve tracer diagrams, showing the relationship between Gate 1 and the drain current, are essentially a blueprint for the stable, reliable television set.
