The second gate acts as a shield between the input gate and the drain, significantly reducing Miller effect capacitance. This provides better stability and higher gain at VHF frequencies. Automatic Gain Control (AGC):
The 3SK41 typically comes in a metal-can package (TO-72 or CAN-4) with four pins. Careful attention to the pinout is required to avoid damaging the device during installation. 3sk41 datasheet

The isn't just a part number; in the world of vintage amateur radio, it’s often remembered as the "silent hero" that cleaned up the airwaves. The Legend of the 3SK41
Today, the 3SK41 is considered an part. For restorers of vintage gear, finding an original 3SK41 in its classic CAN-4 package is like finding a piece of gold—a small, four-legged silicon key to unlocking the pure, quiet reception of radio’s golden age. 3SK41 NEC/HITACHI/MOTOROLA IC Chips | Censtry architecture
Finding an original 3SK41 can be challenging outside of specialized "New Old Stock" (NOS) electronics vendors like Jotrin Electronics , UTSOURCE , or LittleDiode. If you need a functional substitute for a repair or layout emulation, look into these common alternative components:
