mostly just the tempest attract mode. So there could be some unknown problems with this.
It is also very possible that some other resistor values might need changing in the voltage
regulator to compensate for the lower input voltage. (Lowering R905, R906 and R913 come
to mind. And it might be a good idea to re-route R917 to a position in front of the pre-
regulator.)
By dropping the voltage with a pre-regulator you move much of the heat dissipation to the
regulator and away from the HV regulator. This seems like a good idea and should
probably be investigated further.]
