A bunch of my email delivery posts are out of order and missing some [for lots
of groups].
I’ll comment anyway.
Notice that there is no smoothing capacitor in that diagram [if we are looking
at the same one].
This means that with the halfwave rectifier you are going to get pulsed DC
rising
The main reason for not using that circuit is that I don't have that
transformer to hand though I do have many DC power supplies available and
I just wanted to get the voltage right.
Having looked in to it in more detail is seems that it's just a half wave
rectifier which should yield 0.45 x
Hi Michael,
I accept your offer of $300 shipped for the (6) Z5660M + (1) Z5670M + (7)
sockets.
The IN-18s sold just 30 minutes before!
Please PM me with your PayPal email and I can send you an invoice.
Thanks,
Kevin

Kevin,
I’ll offer $300 shipped for the Z5660M setup with sockets.
I’ll offer $240 shipped for the IN-18’s.
And, I am interested in the projects you have in mind. J

Actually I found an INS-1, and when I attached the INS-1 I got one cathode to
light up on the GS10D. I’m thinking that the problem now is the cathode
resistor, now I’m trying to figure out which one that is.

Mmm yes, quite right. At the absolute minimum striking voltage the
formation of the glow will be slow (potentially many seconds),
ambient light dependent and these days pretty uncertain as the tube
will not likely conform to specs after such long storage (we know that

guess that the data on how long they will survive is incorrect in the
datasheets under those conditions. Just 1000 hours for one digit

If they have become slightly out-gassed or cathode poisoned they need more
than 450V.
Nominal voltage is 475V in the datasheet and they need more than that - I
have a few that work well when driven at 550V and one that worked well
closer to 600V but not at nominal voltages.

I measured 448V anode to cathode, and changed the anode resistor to 220K. I’m
starting to worry that the tube may be bad. I tested it with a plasma ball and
it lit up. However, the base is now loose on the tube, and I don’t have the
plasma ball with me at the moment.

The INS1 is used as part of a relaxation oscillator to generate guide
pulses to step the tube, so if that were the only issue, yes the tube
should still glow.
However, the GS10D has
Should the Dekatron still glow?

Thanks I had s feeling that it was important.

Ah OK, 0.318 x input volts so about 32v DC?, is that correct?

Its been a while since I needed with this kind of thing. The 110v is half
wave rectified, does that mean that roughly 55v DC is presented to the tube
via the series resistor then the 5v logic levels are switching the
individual numbers on and off? No need for 170v DC from a nixie PSU type
thing
Ronald Dekker, www.dos4ever.com, wrote about the Z550M/ZM1050 in the
Elektor Magazine #12-2009 on pages 76 & 77 where he showed the circuit
below, which is probably the simplest way of hooking it up, from that you
can design your own circuit quite easily.
