Multiplexing the Nixies (fast)

A test for multiplexing two Nixie tubes. In this circuit, all the corresponding cathodes of two Nixie tubes are connected together in a bus structure. The anodes of the Nixie tubes are switched on one by one and the selected cathode is activated for every digit. This test is fast enough (anode turn on time is 10ms for each tube), so we get the illusion that two digits are on simultaneously. The high voltage transistors used in this circuit.
