 STOCK DIGITAL DISPLAYS Numitrons, Panaplex, Dekatrons, VFDs and LCDs  Skip the INTRO, Go RIGHT to the CATALOG of STOCK TUBES!
These are the various Displays and Display Parts we have on hand from Burroughs, National (Wang), Raytheon, NEC, Amperex, Philips, Numitrons from RCA, and even Panaplex neon displays from Beckman/Sperry. To save you some frantic email, YES! we DO have sockets in stock at this time, but keep in mind many of these are solderable types if you are experimenting or making clocks, and of course, for repairs and retrofits, the socket is already there. We have some new (NOS) and some tested pulls  available. All Nixies have good or excellent element visibility, and none have blackened fronts. We are very picky about what we buy and sell, you can be sure these are worth having.Lots of new NIXIE data just added for your reference. Please note that over-current makes the tubes blacken, and seriously shortens tube life, limit average current to 2.5-3mA for most tubes. NAVIGATION: To make your life easier, and help you find exactly what you want, we have broken the on-line equipment catalogs into smaller sections. Just CLICK on the item you are looking for at the left, to see the matching catalog. Large graphical catalogs are a bit SLOW, so please give them a bit of time to load. The top header of each catalog is largely the same, so don't think you are stuck in one place! ORDERING: You can order anything here just by picking up the phone, and calling +1 (250) 769-1834 during normal office hours, 8am to 5pm, PST. We process VISA/MC orders immediately. You can also send your order by FAX at: +1 (250) 769-4106. Or, EMAIL YOUR ORDER HERE! SHIPPING: Canadian ExpressPost (NOT regular mail, this is like US Global Priority/Courier) Rates: To USA destinations, shipping and packing minimum of $23 for any insured, trackable air shipment up to 1kg (typical delivery within 5 business days), Canadian destinations are typically $10-14 (delivery within 2-3 business days). It is also possible to ship uninsured, untracked, small packets (250g max.) for roughly $12-14 to the USA, but delivery delays can be up to 8 weeks according to the US Postal Service, and so we cannot recommend it. Virtually all of our shipment failures have been because of this method, so it should be used with caution. We have an extraordinarily good success rate (better than 99.9%) with ExpressPost, so we highly recommend it, especially for one-of-a-kind items. It is cheaper than couriers, trackable, more reliable, fully insured and goes almost everywhere. Shipping/handling to Europe, Australia, South America and other overseas areas via Canada Post International ExpressPost air mail insured service or Canada Post International Air Service where ExpressPost is not offered is $51.00 for parcels up to 500 grams/1 pound. Shipping and packing via regular mail to these locales is $22.00 for parcels weighing up to 500 grams/1 pound. This service offers no guarantee, insurance or tracking and we then accept no liability for loss or damage. Transit times are unpredictable by this method. E-Mail Susan if you want a quote for shipping to other destinations, or for something heavy. Sorry, we can't safely send individual small parts in a regular letter envelope, they get destroyed by the automated handling equipment. We can also ship FedEx or UPS when time or weight is critical, and over-night FedEx P1 shipping is available. Note that our pick-up cut-off time is noon for FedEx. There is a packing charge for large equipment, see the FAQ for details. If we have your valid data on file, you can just click on the ORDER email link to place an order and indicate your approval to bill, and we will do the rest. If this is the first time you have dealt with us, you can phone (250) 769-1834 or FAX +1 (250) 769-4106 the billing info, or send it by the email link, as you prefer.  CONDITION: To answer your questions, YES, we completely inspect all new surplus and used parts, and do not offer any we feel are substandard. Those are normally scrapped or may get offered as-is in the HOT DEALS section, or here in a bulk lot with the condition clearly identified. If there are any marks or detracting features, we clearly state them in the listing.

 E1T / 6370 |
Valvo E1T / 6370 miniature CRT beam counting tube One of many technologies that predates Nixies, these tiny CRT-like decade counter tubes toggle the position of a brightly lit blue/green rectangle from one digit to the next with a serial pulse input. They were used in some early lab counters, and are visually very attractive when lit. As I recall, their top speed is about 10Khz.They are very old stock, dated 1970, so they are strictly as-is, no returns. All look good, getters intact, but after 37 years, I am just not so sure they still work correctly, even though they came to us as good used tubes, still operational, but we cannot test these here. They use a 12 pin B12E Duodecal socket, we have a couple left.
Full factory data sheet HERE in PDF format, includes full operating circuits! The tubes are marked E1T, the E1T number is the one most people are familiar with, 6370 is the industrial number. I do not see any easy way these can be used in a clock, as they have no intermediate pulse take off, only a full decade carry output. Still pretty cool. You can see more data on these counter tubes, and how they look illuminated at Akes tube site.

Just Arrived! Reflector IV-16 7-Segment Numitron Displays From the Reflector factory in Russia, these are new, high quality Numitron (incandescent filament) 7-segment displays. Operation requires 3.15-4.5V typical per filament segment, at 17-22mA. Easily driven by 7447 type drivers (with an added 1N4002 diode or two in the common VCC return of the display to drop the required voltage). Flying leads require no socket, very easy to prototype for clocks and other projects.
