One idea Ive not tried is to take a regular 4CX250B and remove the
radiator (they are soldered on) and then make up your own solid block.
Or saw off one side of fins and replace with a brass plate. Then mount a
muffin fan on top of the cabinet to draw out some heat thru the
remaining fins while another fan blows on the heat sink.

Doesn't all this sound cost-inefficient, somewhat?

Are you in desperate straits to get this particular
machine configured with so irregular a design?

My next question is directed towards the
RF Circulating Current model, as yet-unbuilt,
that extensive modifications in an untried
cavity will produce......

However, science for the benefit of learning
is fruitful at any expense.
