I made a one off MAX1771 supply following Nick's guidelines, as best I could using thru-hole parts, and got very impressive results. Not quite, what Nick got, but still a lot of power..

I haven't compared them with the MAX1771 design, so I can't say if its more or less. They can still output significant current from just a 5V in, if that's needed. Taylor's day job, is designing supplies, and he uses a custom transformer. The claim to fame, on my units, is that the kits are cheap ! Its not the most efficient design, its max output is less than the ones above. It still, however, can power a 6 tube IN18 direct drive clock. Thanks to the Chinese for using the MC34063 in the millions, in USB car chargers, that chip's price continues to fall. Mine are kitted from all "off the shelf" parts. Of course my supply is a better design than the first supplies, I encountered, that used the MC34063. With the optimal coil (which doesn't come with the kit), my MC34063 can output close to 10W. I think the MAX1771 can do 20W (120mA @ 170V). Those are the max numbers. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
