The linear have been constructed by me (if you mean the manufacter of linear
amplifier).
The prototype have been constructed by schematic designer and you can see a
photo here:

Also, this linear have been successfully constructed by another radio amateur.

Both of these linear are using International Rectifier IRFP360 mosfets.
I use this time Siliconix IRFP360 mosfets. Both of amateurs claims that
their linear amplifier gives at least 450w r.f power at the outupt
stage.

Are you using the same manufacturer as your friends?
If so, yours should be the similar performance unless
something is wrong.
