Nixie Clock Parts
Spare Tubes: $20 each

nixies_tiny.jpgI do sell spare tubes for $20 each.  You can use this link to add spare tubes to your order. Spare tubes are only offered with the purchase of a clock or kit, or for those who have previously purchased a clock or kit from

Pictured at the right are two IN12 nixie tubes (left) and one IN14 tube (right).  The color of the plastic base on the IN14 tubes will vary.  If you order more than one spare tube, I will try to match the colors of the bases to each other.


IN-12 Spare Tube: $12


IN-14 Spare Tube: $20

International Power Adapter Upgrade: $10

These power adapters are for the IN-14 style clocks, which use 12V DC.  They will work anywhere in the world, regardless of your local line voltage (120V, 240V, etc.), frequency (50Hz or 60Hz), or plug style.  The adapter comes with 4 interchangeable outlet connectors, so the power adapter should work with nearly any plug outlet style, including European, Asian and American styles.

Please note that these are for sale only with the purchase of a clock or kit.
