I'm certainly very interested in this discussion as I'm contemplating a
water-cooled 23cm amp project shortly.

One thing that you do need to consider in cooling a tube amp is the
conductivity of the coolant. It's not a concern in a race car, but when
there's 4kV+ at the cooler, it certainly IS a concern in an amp. This
rules
out any use of salt. Does anyone know if Glycol or "Water Wetter" makes
the
solution conductive at all?
There's also corrosion problems to consider. As I understand, Glycol-based
coolants also contain corrosion inhibitors. Would corrosion be an issue in
an amp using just distilled water?
