David,
Thanks for the encouragement. I wholeheartedly agree with you regarding eBay. I had a chat by email with this guy.... apparently, there are 'military warehouses' in Russia which dispose of unwanted, surplus stock to bonafide dealers only; the public can't buy from this source. Therefore a lot of varied and interesting items appear from time to time. He says there are no component shops or outlets in Romania, so he runs his business through an eBay store.
The 'nixies' I bought from him are VU meter bargraph displays with a column of orange, neon light driven from 0-5mA instead the usual numerical indication. I wanted something different and there are hundreds of nixie tube clock designs out there using the usual 0-9 tubes. I haven't been able to find a clock using IN-9 or IN-13 tubes so thought this would make a good project. I've decided to use all-Russian components where I can and am considering using those minature valves for the dividing stages and counting logic as they are so cheap and look like fun to play with.
Sorry... I'm wandering off topic here so will start another thread when I have got a basic design clear in my head.
