Although an excellent wide marching range tuner it will handle the power as well.  If one is  experiencing SWR drift, that indicates the disc ceramic caps are getting hot and changing value.  They are adequately rated for voltage but not for the current under certain match configuration. 
   
The better solution is to remove the 8 - 220pf caps and replace them with 4 of the Russian 470 pf doorknob capacitors.   There is room to mount them to the bottom panel an the issue will be forever gone.
