The 9205 IN-1's are perfect for experimenting. They are inexpensive, easy-to-find, and have similar-enough characteristics of better tubes that you can use them for some prototyping. Just be aware that IN-1's use a bit more current (3mA) so you will need to adjust your anode resistor (or current-limit if you go that route) when you change tubes.
They might work OK in a clock that is not displaying 24/7, or perhaps a digital multimeter (yep, it's on my drawing board...) I only know from my experience that displaying a single static numeral on an IN-1 with that date-code is going to cause tube failures pretty quickly. BTW, dont waste time/money on sockets for the IN-1 (or A101 dekatron for that matter). I use crimp-connectors (TE Connectivity AMP Connectors 350415-1 , available for cheap from DigiKey) soldered to a wire, then covered with heat-shrink tubing. It works perfectly. I have about 20 of these boogers, and I was thinking of arranging them in a 4x5 matrix into an "idiot box" where they all display numbers randomly. I've come close to putting a near-dead one in a microwave oven and documenting on youtube, but I have too much admiration for nixies to do that.....even THESE nixies. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
