I think the Hammond page has a small tutorial on Power suply design using "Brute force" transformers Snoop around http://www.hammondmfg.com/ -- Charles MacDonald Stittsville Ontario cmacd@... Just

Hi! For all who asked me about the IN-8 sockets (tubes, and single contacts): They are now available at my little shop:

Greetings, Sorry for the commercial taint, I have a complete working E1T counter on Ebay here http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=290455311019&ssPageName=STRK:MESELX:IT And I am

I got mine a couple weeks ago, been buried in projects and haven't had a chance to play with it yet. Curious what people manage to do with these things.

Additionally when you use a full wave bridge, the DC voltage out is higher than the RMS AC voltage in, so the RMS AC current on the transformer secondary is higher than the DC current drawn by the

IIRC the power supply in my 6 tube B7971 clock delivers about 50mA at 180V and that is plenty. There are diminishing returns when it comes to increased brightness for increased drive current, and tube

I just called. Turns out that orders are well backorders. Chronos watch = 1-2 weeks back order. MSP430 Kits are 6-8 weeks. My order was on July 2nd. ETS (shipping) is end of August. Michail

Oh yes, definetely. Thansk a lot! Jens

yea the glasss ones are hard to swallow ,need about a gallon of water! so now i can take that dekatron spinner off my forehead to prevent bone loss?

Apparently dekatrons help prevent bone loss (osteoporosis): http://www.starkepharma.com/pharmaceuticals/?product=nandrolone-decanoate Its for a drug, not the tube we have fun with, here in this group.

In DC watts is Volts times amps. IN ac it gets a bit fuzzy because the volts may lead or lag the current. (depending on the nature of the load.) still 35/115 is about 300Ma... If you check the hammond

Can I effectively drive the 6 B7971 tubes with 65mA? Direct drive not multiplexed! Sent from iPhone off & running

Oh many thanks for the quote. This mailing list is a wonderful resource, but it is sometimes hard to search for specific topics. Thanks for your help :-) I think I might be onto one of those monkey

That "percent sign" sounds like it has the same function as the upside-down 8 that most every normal nixie tube has, that no one ever seems to talk about. In a normal nixie tube, this electrode is

I found the last post from A.J. Re: Burroughs Nixie.

http://www.tayloredge.com/storefront/SmartNixie/DataSheets/Datasheet_1363-1364.pdf From figure 9, that's 65mA at 180V, 16V in. (45mA is for 12V in). jt

just how much power could you get from the old school ,N51X 115vac to115vac isolation transformer @35 volt amps AC ?(so what do that mean) through a full wave bridge at 400 vdc and a big hunking 100uf

That's 19W; the conversion below can give you the same number of watts as the original PS is rated at whatever voltage you want: http://www.tayloredge.com/reference/Circuits/GPC41-5G/index.html I had
