The anode air cooler could be removed. In its place, a small copper (or
aluminum) liquid cooling block --considerably smaller than the original air
cooler-- could be made in a machine shop in a couple of hours.
This block would have a bored hole .001-.003 larger than the anode. There
would be a slot sawed from one side of the block through to the hole, and
this slot would allow a through bolt to tighten the bore around the anode.
A single "R" hole would also be drilled through this block, and each end
tapped with 1/8" NPT pipe thread, where the cooling liquid would flow
through. A poly tubing fitting gets screwed in each end.
I would use distilled water, and replace it regularly. It's cheap, readily
available, and is a better coolant.
Capacitance issues solved. :-)
Here's how one guy did it, but it looks more complex than what I described
above.
