I had a major Nixie tube binge a while back and spend a lot of time searching eBay for tubes and related items. I only found a small handful of US manufactured 74141 chips. I bought a half dozen just to have them for nostalgic reasons. As Jonathan said, the Russian equivalent KM155ID1 is much more readily available and cheaper for practical use. In my experience you can find them for around $1 each or a little more. This eBay listing http://www.ebay.com/itm/260942702575 is for a seller from whom I have purchase many Nixie related items. The price is high, but consider the free shipping from Ukraine. If you want higher quantities, he will usually provide a better price. Chris F.

Are 74(1)41s still made or available?
The Russian equivalent is readily available.
Thanks, Jonathan
