Default Yaesu FT 901DM RF Power Problem

Hi,
I wonder if anyone out there has a Yaesu FT901 as I aquired this but as I have not owned one before I need to know if it has a problem or not?.
The Transceiver has not been modified or got at in any way in fact it looks original but as some people have told me that it was not meant to produce 100W on all bands ? this seems strange to me but I thought I would ask the question as I have the following RF outputs all taken into a 50 carbon resistive dummy load with AV20 rms reading power meter:
All readings taken by using the "Tune" button and preselect plate/load peaked
160m (1.950) = 100W
80m (3.800) = 100W
40m (7.300) = 60W
20m (14.300) = 80W
15m (21.300) = 80W
10A (28.300) = 50W
10B (28.800) = 60W
10C (29.300) = 50W
10D (29.800) = 40W
If someone who has one of these could say if this is correct or not I would be grateful.
Best Regards to all
Richard
