Unlikely. I have fourteen IN-18's in my kitchen clock, and none has failed. These are extraordinary tubes that look great and last a long time. On Wednesday, June 15, 2022 at 8:05:09 AM UTC-7 lawill...@gmail.com wrote: > Thank you to everyone that responded with the answer. Never would have >

Thank you to everyone that responded with the answer. Never would have guessed this. To follow up; is it common for the capsule and wire to come loose and float inside the tube? Depending on where the wire rests it shorts digits together. On Wednesday, June 15, 2022 at 10:43:59 AM UTC-4 Paul

It is a capsule that contained mercury. It was heated up when the tube was manufactured to release the mercury. The addition of mercury to the tubes vastly extends their lifetime. On Tuesday, June 14, 2022 at 10:15:13 PM UTC-4 lawill...@gmail.com wrote: > I recently got some IN-18 nixies and
