The retrofit kit is just the tube plus mounting hardware (it's 
physically quite a bit smaller than the HP tube).  There's no additional 
circuitry, and no electrical changes to the HP chassis, other than the 
several tube-specific components that you need to change to adjust oven 
temperature and C field centering, etc. (just like you need to do when 
changing HP tubes).
