Sven, do NOT go by my power supply layout. The two 1 ohm resistors should be replaced with a 0.05ohm. Also my layout is really bad. It works now, but I had to change the feedback path, ie move the pot. It would be better to move the FET so it sits at one end of the MAX1771, not at 90ยบ as I have it. Generally, if you are going to get a double sided board made, go by Nick de Smith's layout on his website: http://www.desmith.net/NMdS/Electronics/NixiePSU.html The MAX1771 is very picky - I don't get much success with it. It is prone to spikes on that feedback loop and won't regulate. John S -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
