To prevent electric shock, the power must be turned off when plugging and unplugging the tube. Children should not touch the exposed circuit board while working. Please use your own safety measures.
Tube conversion sheet 6N2/6N1 is 12AX7 ECC83, 6N10 is 12AU7 ECC82, 6N1/6N2/6N10/6N11 is up, 12AX7/12AT7/12AU7 is below.
Size: diameter 25MM, height 27MM (including stitching, stitch length 10MM)
Material: double-sided board, board thickness 2MM, copper thickness 1OZ, copper plated silver tube socket, copper nickel plated pins
Note: The precondition for this tube socket is that the 12AX7, 12AU7 and 12AT7 series tubes are 6.3V, i.e. 4.5 pins are connected to 6.3V and 9 pins are connected to 6.3V. Use 12.6V to connect to 4.5 pins, if 9 pins are empty, this adapter will not work. If you are unsure, you can judge by measuring the pin 4-5 in the original vacuum tube socket.
