I have one of those I got from Gareth. Heavy is a good description. They work well, if rather inefficiently. 28V internal PSU, supersonic wind tunnel cooling system.
I was using it at 15W as a driver for one of Arthur, G4CPEs 300W PAs, when I thought I needed high power when GB3HV was at the old site. I didn't need it however as despite the unpromising path, I found I could get in with a couple of watts.
