NCH6300HV, Powering Up Your Nixie Tubes & Magic Eye w/ Ease

A 100V-235V DC-DC boost power converter for vintage vacuum tubes. It takes LiIon battery, 5V USB, or 12V as inputs. Easy to use.

126 backers pledged $7,869 to help bring this project to life.

Story

(For the latest update, go to the bottom of this page)

What is NCH6300HV?

• Nixie tubes look unique, pretty, and are fun to play with. Powering them up is not easy though, as they require 170V DC voltage to ignite.
• We designed the NCH6100HV in 2012, and it has been very popular in the nixie community.
• 8 years later today, it's time to update it to the brand new NCH6300HV.
• The NCH6300HV is 19% smaller in footprint, yet almost double the power compared to its precedent. They are pin-to-pin compatible so just drop in and it just works with a minor tweak.
• The design has been firstly tested in our Omnixie Plus clocks to replace the old model, which has been in mass production since May 2019.
• Omnixie Plus powered by NCH6300HV design (with ZM-1040 Nixie tube)
• Omnixie Plus powered by NCH6300HV design (with IN-18 Nixie tube)

Why NCH6300HV?

• NCH6300HV DC-DC power booster that succeeds its precedent, NCH6100HV, with 19% smaller footprint, higher efficiency and almost double the output current.
• Its sibling, NCH8200HV, was used by many nixie enthusiasts and professionals. For example, the Puri clock by Dalibor Farny uses our NCH8200HV as power supply in its slim base for years.
• The most powerful and adaptive 6300HV can power more 10+ the largest nixie tube at low voltage. See how it powered by 5V DC source.
• And yes, you can do it with Li-ion battery too!
• NCH6300HV uses Lithium Ion battery to power up IN18 tubes The spec comparison among 6100HV, 6300HV and 8200HV.
• Feature comparison
• 12V DC Input can power up 12 the large IN-18 nixie tubes with ease. It can light up ~23 of them (100mA max) if active cooling is properly implemented.
• 5V DC Input can power up 10 pieces of IN-18 nixie tubes. No problem~

Our story

• Our story
• We are Nixie veterans located in the San Francisco Bay Area and Guangzhou.
• Zeyuan Yan, the nixie tube expert, is the designer of NCH6300HV DC-DC power booster that succeeds its precedent, NCH6100HV, as well we many Nixie/VFD clocks.
• Aiden Fang, garage guy, post-doc and the tech guru worked at Lawrence Berkeley Lab, is the maker of various Nixie clock DIY KITs and the creator of the Omnixie® brand.

• We are top rated Nixie clock maker and seller both on Amazon and eBay. We are badged with Amazon's Choice in multiple Nixie lamp categories and having the highest 5 star customer satisfaction rate.
• Thanks for all the reviews of our customers. We are honored to provide the best products as well as the fulfillment services to Nixie lovers. This is our promise:
• Great product quality Fast shipment Dedicated customer services
• Video VoiceOver: SF

* Note: As nixie tubes were manufactured more than 30 years ago, some of the tubes may not appear as new. We collect them over the years from different vendors/surplus/markets, and they may be used or new old stock. Therefore we can only guarantee they will function as expected.
