The temperature problem is a good clue; there must be a larger transistor not shown in the schematic that is the actual driver, and I suspect it's overheating. Does it have a heatsink, and does it get warm/hot ?
Does the supply work correctly when illuminating shorter segments of EL wire ? The transistors shown in the schematic are probably pre-drivers. They *should* continue to operate correctly even as the EL wire starts to dim. You can confirm this with your scope. What frequency/voltage are you seeing on the HV ? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
