Although, if you are using a voltage doubler to get your HV supply, you
will find that the supply sags as current increases. That's why using a
voltage doubler for the nixie HV is a hassle: as you increase nixie
current, HV supply voltage drops.. Use ohm's law to calculate the value
of your pot

No, won't hurt 'em, just adjust th
In the Mike Harrisson design (at least for US power), the HV nixie
supply is ~250vdc. I think that 200-210 should not pose any problem
provided that the current limiting resistor is appropriate.

Hi guys I'm new to the group, I have built a couple of clocks before,
I'm working on a IN1 nixie clock with an OG4 dekatron and a IN9 neon
bargraph (seconds) at the moment, it uses a software module for the
pic micro to decode the msf time signal.
All the electronics (well nearly all) and software
