There are no IC’s on the board with the 2n7000, just some resistors, leds, nixies and the connectors to driver, controller (led pwm) and psu. I replaced the 2n7000 with BC548 and 4.7K resistor (patch picture). One of the driver boards on the picture has two HV5622 and the other one 8 x 75HC595 and 64 x MPSA42 transistors.
