Did you wire both trigger electrodes together, the Z660W have two trigger electrodes but the ER32 only one.
You must also check that the minimum anode current is 5mA as the Z660W might otherwise work unreliably in some situation according to the datasheet. You might also have to check the capacitor connected to the anode as well as the anode resistor as those form the circuit that extinguishes the trigger tube, turning it off, and if they do not work properly the tube might not be fully extinguished and then it will turn on again - the capacitor might leaky opr any of the other capacitors/resistors surrounding this trigger tube might be leaky or having the wrong value. Also don't forget to replace resistors with types that can handle the voltage in these circuits, many cheap resistors sold today only tolerate 125V or 250V which won't do in circuits like these! /Martin -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
