You can find a PDF-file on the IN-9 & IN-13, from a Russian book, with the original Russian and a translation made with Google Translate here: https://drive.google.com/open?id=0B2XLFMydwkBgc2lhSEk5WXgxLXc in the TEMP folder here at the forum.
In most designs that I've seen in Russian books the IN-9 is almost always driven by half-wave rectified voltages and is usually used to measure an AC mains voltage or similar voltages, just like the first schematics shows in the document. The IN-13 is mostly used where you want some precision and also when you need better control of the ignition of the tube. /Martin -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
