Magic Eye Winker • The senseless circuit

Based on the same dimensions as the tube board from the Magic Eye VU-Meter (50 mm diameter) this gadget does only one thing: "Winking". It is powered via USB* and all 6V heater tubes can be fitted. Solder bridges on the bottom side will connect the signals according to the socket needed for the tube. These tubes can be fitted: EM80 / EM81 / EM84 / PM84 / EM85 / EM87 / EM800 / EAM86 / 6BR5 / 6DA5 / 6E2 / 6E3P / 4FG6 / 6FG6 / 6DH7 / 6HU6 * it can also be powered from an external battery pack up to 18V, so it is possible to fit tubes with different heater voltages like the UM80 with 19V for example More on www.Nixiekits.eu
