I just finished testing and sorting all the Nixie tubes we got in that were left over production stock (from long ago). You may recall I offered sets of 6 new tubes a few weeks ago, and they went quickly. These were referred to as "Super" size tubes by Burroughs, the factory data sheet is here:
This tube is long life and wide viewing angle rated, and still runs on the regular +170VDC supply. They have the same base, socket and pin-out as the famous B5092. Great looking tubes when lit!
These are in two groups, "appear to be new" and "probably used", but still look great. Every tube has been thoroughly tested, and every marginal tube was kicked out, these are from the early 70's so there were a few that just didn't light correctly, or had base flash-over.
Want some "duds" to experiment with? ask and I will toss a few in with your order, I always have a big reject box).
For list members only, a set of 6 "appear to be new" tubes is US$139,
and we will throw in 6 NEW chassis sockets. We can ship anywhere in the USA or Canada for $23 (expresspost) or less if you want uninsured surface mail. We can take visa/MC directly for orders, or Paypal if you want to cover the exchange fee.
The "probably used" sets of 6 are US$125, also with free chassis sockets. I can make up about 4 more sets in total, so email me if interested. You will love these for clocks, the big digits really look great, and of course the true-form characters and US-made quality of these tubes is a real bonus. No, these are not up on our web site, this is just a one time offer for list members. We get these so seldom, I thought they might be a nice summer treat for everybody here to experiment with, and a nice change from Russian tubes.
all the best,
