Head a quick browse and from what I can see the first part they are discussing the design, its output power, the devices used and power supply requirements. The amplifier design uses the rd06 & 70 devices, for another good design with them search 'free radio Berkleyb(frb) 70 Watt instructions/ manual' something like that. Its an American design, very similar.

Good luck
