AS with any high powered RF device -- or even Pentium 4 microprocessors --
thermal design and proper thermal construction is CRITICAL,
I would use a copper spreader for building this amplifier due to the close
proximity of the 4 RF transistors.

This is NOT a beginner's project or kit
Here are other web sites with thoughts and construction details, notes.
