Looks like 70-80W on 10m.  The radio thinks it's a full 100W.
If I go down from 10m power goes up slightly, never quite 100W but close enough 
for me.

 Hi Shawn,

what's the output like on the bands 20 and above? I recently restored 
one and spent quite a bit of time chasing  my tail. I had full output on 
160-40 but it dropped off rapidly above that.

I eventually discovered one of the final transistors was open. The 
little "3D structure" of resistors/caps they used to bias the 
transistors had a bad solder joint that had opened up and this killed 
the transistor.

Take the final section off and give it a good visual inspection, and 
maybe even wiggle things a bit in that area and you may find the same thing.
