Eric, One subminiature thermionic valve will not draw much more power than an EZ10B!
I understand if you want to keep it all cold cathode, I did the same a few years ago but never found a cold cathode tube that worked at those speeds in an oscillator circuit. There are a lot of books on crystal oscillators and I think that you could use a crystal oven with either a 1MHz or 100kHz crystal and have a very stable oscillator with those, the TCXO might be somewhat better but with the lower frequency you can just copy a circuit from any old frequency counter. /martin On Monday, 10 February 2014 11:20:12 UTC+1, Tidak Ada wrote: > John, > Concerning thermionic tubes you are right, but my goal is to use only cold > cathode tubes, surely not in the last place to keep power consumption low. > A divide by 10 counter, even with submini's or Nuvistors consumes a lot of > Watts... > > eric > > -----Original Message----- > From: [email protected] <javascript:> [mailto: > [email protected] <javascript:>] On > Behalf Of John Rehwinkel > Sent: maandag 10 februari 2014 3:54 > To: [email protected] <javascript:> > Subject: Re: [neonixie-l] Elesta EZ10/A/B tester refurbished! > > > I have a 4MHz TCXO that I have to scle down to 4, 2 ,1, 1/2 and 1/4 Hz. > The first stage will be unfortunately made with some TTL, because of I > dont > know there is any tube that is able to do the job. > > I can think of lots of tubes that can do that easily.
