Re: [neonixie-l] re: 6 - B7971 tubes

Speaking of B-7971's, on a whim, I just did a search on eBay for the rarer cousin of the B-7971, the B-8971. Amazingly, I found one. As I haven't bid on this type of tube in a while, I'm not sure what the going rate is these days, but $200 seems reasonable, given how rare they are.

Looks like there's a manual for sale on ebay right now, complete with schematics. You're in luck. http://www.ebay.com/itm/Sperry-Corp-MK-8-Radar-Service-Manual-w-Schematics-44281-/300912947775?pt=LH_DefaultDomain_0hash=item460fcf323f -ub On Fri, Mar 7, 2014 at 5:55 PM, Morris Odell

Re: [neonixie-l] Slightly OT - 2kV voltage isolation?

Why not just make your own optocoupler? Fill a lexan or acrylic 10 cm tube with clear, slow-setting epoxy and then affix an IR led on one and a darlington phototransistor on the other end, with these two components serving as end plugs for the epoxy. Then paint the unit black with a low-voc

Re: [neonixie-l] Re: RFT Z568 for sale on ebay ;)

Wow is right... Rare item status will do that to the going price... Consider the going rate for Rodan Tubes, if and when they are ever offered again on Ebay. I imaging that they could easily go for $1200 each. A set of F9020AA's would probably fetch even more. -ub On Sun, Nov 28, 2010 at
