You don't have to detune it or run a big amp like the 1200.  First, sell the 667.  You can buy a Texas Star DX500, send your radio to DTB and tell him to set the radio up for that amp.  With your variable power on low you'll be dead keying about 1.5W.  When you turn off the amp and turn your variable power up it will act like its normal self.  That is what I did with mine.  I have a 95t2 matched with a TNT 600HD.  It isn't a Texas Star 500, but it uses the same 2879s.  My Galaxy is set so I can turn the variable power down to 1.5W on low power for the amp.  When I turn the variable power back up, I Dead key 35W and peak out at about 140W.   It works just fine.
