Wow, great catch. I wouldn't have thought to ask if he was running the
HVPS through the 7805.. Should have done the math. :)

Hi - I was running it from 5V :(
Moving 1 wire (to run HVPS straight from input voltage) :-
9V in - 390ma
12V in - 320ma
Just about half the current - everything running cool.
Thanks !

Are you running the HVPS from the 9V or the 5V? You should definitely
not use the 5V for the HVPS as it can run from up to 16V and at a
current inversely proportional to the input voltage.

It is a while since I built a Nixie clock. Just finished one using
Moses chip, Tayloredge hv psu, and 6 IN-16 tubes, 2 blue led's.
Standard 7805 regulator, fed from 9v. Curent is almost 600ma when
running. Regulator gets pretty hot (though ok with heatsink). Nothing
else gets warm and clock seems to run OK. Does this seem normal?
Would appreciate your thoughts. Thanks, David
