I have one of the last production 1w units. With the FA66 calibrated, on 
30m at 100% power as indicated on PWSDR I get 0.45w out measured on some 
accurate lab test gear.
I have heard that the 1w rating was a 'nominal' value, and half a watt 
or so when properly setup was fairly typical. As I use it mostly to 
drive transverters, the lower power is fine for my needs.
