yep, the ts2000 has great finals for the VHF and UHF PA. that radio will 
perk along at 100 watts on VFH all day if you want it to.
it has a good sized chassis wich acts as a great heat sync for those hot 
transistors.
most mobile radios just don't have enough heat sync to take away the 
transistors heat and therefore most have circuits to pull the power back or 
shut the radio down when it gets too hot.  The ts2000, unless you are 
operating in really hot weather without AC, will get rid of most of the heat 
through the very efficient fan and the massive heat sync.
now if that radio was a yaesu, it would probably go into some sort of major 
melt down after 5 mins at 100 watts like the mobile radios do after 3 
minutes at 50 watts.
that said, the TM V7A doesn't have very good heat dispersal either and you 
can't run it in cross band on 50 watts for very long without the top 
becoming hot enough, literally, to fry an egg.
