[Rod Hogg]

I would think you would want a linear taper control for that
Vs a "volume control".

the Valiant has a standard 25K 'volume-control'  pot which was visibly
overheated."

Smoking "pot"? For shame.

"Mouser doesn't even list a 25K, 4W pot, and the prices
charged by the big suppliers like Newark are $25 and up."

There is a simple mod to replace the drive pot with a regular "volume 
control" in conjunction with a TV horizontal output transistor which then
takes most of the heat.  A search will turn this up, IIRC, on amfone.net
