My final solution to this issue is to leave the wires full length. Do not cut them! Slip a piece of small teflon tubing over each wire. Then bend out the bottom end and solder to a dual inline (DIP) header. That way, the tube with the attached header can be plugged directly into a suitable DIP socket. On the prototype IN-17 soldering experiment, these insulators were cut to exactly 1.03 inches in length. Then a tiny soldering heatsink is clipped onto the tube lead wire right at the bottom of the plastic standoff that comes with the tube. The 1.03 inch length of teflon insulation tubing then leaves just enough lead sticking out the bottom end to be soldered to the header pin forks. The uninsulated gap where the heatsink was, is small enough not to be any problem. For the first one I used a 12-pin header. Made this by cutting off a 14-pin header. That then allows the tube's lead wires to be soldered down and kept from crossing. One header pin gets skipped on the pins 7 through 12 side so that the same geometry is kept as is on the tube base. This works out very well. Did a similar treatment on the Chinese QS18 tubes. Did same thing long years ago with a large batch of B-5750 and B-5853 tubes. Those tubes had very short pins from being salvaged from old equipment so for those I wirewrapped on some longer lead wires then soldered those to the header. By doing this these wire-ended tubes can be easily converted into tubes with good solid socket pins. -Chuck On Wednesday, December 18, 2024 at 11:52:08 PM UTC-5 Richard Scales wrote: I would tend to agree - having made this super small clock for IN-17 and now IN-2 - put the two side by side and there is no doubt as to which one is the winner. The only 'issue' with the IN-17 variant is that the tubes have to be soldered in to position. I've been giving away a set of N.O.S. IN-17 with each IN-17 kit as I have a few on hand! - Richard On Wednesday, 18 December 2024 at 20:22:16 UTC Keith Moore wrote: IN-17's are my favorite Russian nixie. They have the cleanest, prettiest glow of any of the smaller nixies, in my opinion. I am partial to small nixies, and these are my fave.

Very pleased to see that this tube has a real 2 and a real 5! Looks bright and clear. Runs at around 1.2 mA at 170 volts using 30k anode resistor. I'd like to hear everyone's opinion and experience with the IN-17 tube. Any ideas or comments? Thanks. -Chuck -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
