I suspect that wouldn't work the way you want. I think that resistor parallels part of the voltage divider in the feedback loop. By introducing a separate voltage, you would reduce the sensitivity of the feedback loop and thereby produce poorer regulation. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
