[neonixie-l] Super easy wall adapter mod: 9V plus 170V at 80mA
Just for fun I modified a Cincon TR1509 wall adapter (9V at 1.4A rated) so that now it puts out the original 9V plus a regulated 170V at 75mA (13W total for both outputs). This requires re-winding the transformer and then adding 2 diodes and a capacitor. The original secondary is 2 x 15T of #24 in parallel and is right on the outside of the bobbin so it is easy to get to. The transformer core has a center pole gap so it is easy to take apart because only the outer legs are glued; I took this one apart with a BIC lighter. The new winding is 15T #32 to replace the original winding followed by 268T #32 in series with the first winding. The 15T winding goes back into the holes for the old winding and the new fly lead connects to a couple of high speed diodes that feed a high voltage electrolytic cap. The main output is regulated to 9V with the original feedback circuits and the new winding puts out a voltage that is turns ratio related to the first. One big advantage is that you don't get the double efficiency hit of an AC-DC feeding a DC-DC boost since all of the power is converted in a single step off the mains. Also, you get the same mains isolation as the original design because you never have to touch the primary... most flyback converters sandwich the secondary between two halves of the primary for better coupling. jt -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

I would be interested in one as well. From what I have seen from the web page, this is a first rate clock/DM. I would be interested to see what one of these would cost. Ron ...Semper Fidelis...

Clever! I admire your patience winding 32 gauge wire; it's pretty fragile. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

My "Thin" wire is #43 or #50. This stuff feels like wire brush bristles when I use it. Running a long time test: 185V at 75mA plus 9V at 100mA. Diode temperature rise is 8C and ripple on HV is 78mV RMS. Going to let it run til Saturday morning (When I need my bench back). -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
