Thanks for all information! Do you have any information on cathode resistors or how the circuit for the reset cathode and auxiliary anode should be connected?
I realise that I might have been a bit unclear in my first message, English is not my mothers tongue. So what I am really looking for is information on how they were connected in real circuits. /Martin On 10 Maj, 01:19, threeneurons <[email protected]> wrote: > On Tuesday, May 8, 2012 5:20:59 AM UTC-7, Dekatron42 wrote: > > > I recently aquired a few Western Electric 6167 dekatrons.
