Hi Andy and group,
I like to heat them for at least an hour before putting any voltage on
the anode since they're old. I prefer several hours. I have tested them
after a nominal ten minute warm up and found them to be fine but I
wouldn't put full HV on them in that time. In any case, I would avoid
4KV and above.
