Hi,
His diagrams point to the low pass filters. Those are so very common they need not be included - merely mentioned. He mentions them:)

No harmonic filters?

I made an RD06HHF external amp, for my QRP Labs rigs and for general use.
I have one of my QRP Labs rigs set for about 200mw output, and pass it via a 3db attenuator.
I prefer to use an attenuator because it keeps the impedance constant at 50R regardless of frequency (RD06HHF is about 200R).
