On biquinary tubes..

I was reading on the builders' forum and Ty had said something to the effect that biquinaries were not compatible with Ian's kits. I have a set of IN-4's that I was going to use to replace the IN-1's in an earlier build of Ian's classic nixie kit. I was under the impression that the 2 anodes could be connected and they could be run in a conventional clock, seeing as they have individual cathode connections. Am I mistaken? I haven't used any biquinary tubes before.

Thanks Ty. I have seen that page. That site comes up every time I do a search for a nixie datasheet and is quite the resource. I assume you were talking about the other biquinary tubes that have common cathodes for 2 digits apiece in the other post.

The main reason I haven't tried it yet is because of it's reputation for early failure due to it being a non-doped tube. Unfortunately the IN-1's currently in the clock also have the same reputation. It seems every week I was disconnecting a digit in that clock because of inter-electrode shorts. It has become rather useless with many digits disconnected so I just unplugged it until I found something to replace the IN-1's.
