I would start with a very practical test.  Take the cover off and 
transmit high power through the existing balun for a while. Stop 
transmitting and feel the balun to see if it is hot. If it is not, you 
don't have a problem. If it is hot, then think about solving it.

Ten Tec has always had pretty good engineers. I find limited value in 
trying to improve on their work.  The only thing I've had to do with my 
229s and 238s is to replace a few of the fixed caps that can overheat 
with high power operation (1.5kW) and certain extremes of antenna 
impedance.
