Re: [neonixie-l] Flip Clock with WWVB

2016-01-27 Thread Tom Van Baak
This is likely JJY and not WWVB. Japanese radio controlled clocks receive JJY at 40/60 kHz. US clocks receive WWVB at 60 kHz; and the data formats are incompatible. /tvb > On Jan 27, 2016, at 4:05 PM, Michail1 via neonixie-l > wrote: > > Thought a few people

About those CD47 tubes on eBay... To me, they look slightly used, or maybe abused during shipping or storage. You can see minor chipping all along the expansion slots of the base. By contrast, here's what the base of a new CD47 looks like:

I agree. It's hard to get faithful photos of the CD47. Maybe because it's large and thus more 3D than most Nixie tubes. In person they do not look weird at all. The digits are very well shaped; a unique and attractive "font". They are gorgeous and gigantic. I share again the positive leap
