[AMPS] Water cooled external anodes

[Chris R. Burger]

Ian's explanation of the problems associated with water cooling an 
external anode was interesting.  I managed to delete it before 
something from my distant past crossed my mind, but here goes:

I've seen some Heath Robinson contraptions where the external anode 
(i.e. the radial fins and concentric shroud) have been removed.  The 
cooling water then flows around the tubular body of the tube itself, 
rather than through the fins. 

This idea may help to facilitate liquid cooling of CX tubes.  The 
kind of figures I remember are a five-fold increase in plate 
dissipation (i.e. something over a kW for a 4CX250B, yielding US 
legal limit output from a single specimen!).
