Note: The premise of using this socket is that the 12AX7, 12AU7, 12AT7 series tubes are powered by 6.3V, that is, the 4.5 pin is connected to 6.3V in parallel, and the 9 pin is connected to 6.3V. If 12.6V is connected to pin 4.5 and pin 9 is empty, this adapter cannot be used. If it is not clear, it can be determined by measuring the voltage of pins 4-5 of the original socket.
The power must be turned off when unplugging and inserting the tube to prevent electric shock. Children should not touch the exposed parts of the circuit board during work. Please take safety precautions by yourself!
Tube Adapter 6N2/6N1 to replace 12AX7 ECC83, 6N10 to replace 12AU7 ECC82, 6N1/6N2/6N10/6N11 on the top, 12AX7/12AT7/12AU7 on the bottom.
Size: diameter 25MM, height 27MM (including pins, pin length 10MM)
Material: double-sided, plate thickness 2MM, copper thickness 1OZ, copper silver-plated sockets, copper nickel-plated pins.
The converter seat with LED has a current-limiting resistor, which is suitable for 6.3V AC filament. If the DC power supply is used, the polarity may be wrong and the light will not light up. Switch the positive and negative poles and it will light up!
