Nice to hear that ! Guess that's why the emphasized the aging process in old neons used for logic. Guess that applies to triggers, too. Kinda makes sense. Great Job ! I love seeing these things ! On Saturday, April 12, 2014 2:44:41 AM UTC-7, petehand wrote: > > Last word on the trigger clock, fr

[neonixie-l] Re: Trigger clock revisited

Last word on the trigger clock, from me anyway: Upping the anode resistors to 43k didn't work as expected. I finally settled on the optimum value at 30k. I swapped the 50 minute tube with its associated nixie driver tube. The ring counted just fine but the '5' never went out - the tube was WAY

Re: [neonixie-l] Re: Trigger clock revisited

Mostly, I do valve ("tube" to our transatlantic cousins) amplifiers these days. Over on some of the UK groups we've been having discussions about the UV risk from Hg rectifiers - it seems though that the glass absorbs pretty much all the dangerous UV I asked the question about a year ago on th

Re: [neonixie-l] Re: Trigger clock revisited

"However, in thiis tube, the metal shell serves chiefly as container and electrostatic shield for the glass bulb, which is required to insulate the contained gas from the grounded shell." I hadn't thought about that! Just enclosing it in a metal shell wouldn't work with a gas tube! - John -

Re: 0Z4G Re: [neonixie-l] Re: Trigger clock revisited

I agree that the "G" version of almost all tubes I can think of that had that designation, were of the "ST" glass shape, except for at least this one odd ball 0Z4G, with the T-7 glass. The GT versions applied to 'any' glass 'tubular' tube regardless of the size, think 6SN7GT versus 5U4GT, etc.

Perhaps I should use something less vivacious, yes. At first I just left the strip light over the workshop bench on (40W at 1.5m) and that was fine as well. I used the pond lamp as I had a spare to hand - it needs to go out to the pond filter box now it is spring. Perhaps a "black light" la

I admire the holy purity of your art, Grahame, to make a tube regulated PSU. I'm afraid the presence in my junk box of a small mains transformer with 200V and 24V secondaries but no suitable heater voltage led me to stray from the path of righteousness and yield to the cheap seduction of semico
