The Pro Nixie Tester is also not available. That's actually the one I had been looking at. I could roll my own from the schematics, although I'm not sure what transistors he's using. IIRC, I had used MPS42A's in a MSP430-powered NL840 design I had done at one time. There might have been a couple of other parts in the schematic that are a little vague but could be worked out.
I need to go through the tubes again and verify it against my spreadsheet. I'm pretty sure I had entered everything I had, and I don't think I have any 5971's. But I do like those :) --jc Save a life; adopt a shelter animal. On Tue, Jan 9, 2024 at 8:50 PM Mac Doktor <[email protected]> wrote: > > On Jan 9, 2024, at 6:25 PM, J.C.
