The 1kW rig with its top off. Everyone wanted to see inside when I took it to Windsor but I wasn't keen... now you can see why! The RF deck is built on a sheet of SRBP board. Below this are the mains transformer and some other PSU bits which sit on the bottom of the box. The LPF is on the left with the c/o relay on top and the fan; then the driver board with the o/p toroid behind. The fets are bolted to the heatsink just under the toroid. The thing on the right is the CB rig which I use as a synth.

From the (almost) sublime to the ridiculous... This is the lash-up I used on 73kHz! It produced 700W from 22V. Ah, those were the days...
