This was sold as a kit for about £700. I bought the transformers from Velleman and borrowed a kit from a friend who was manager of Maplin in Manchester, and made everything else myself, including a different case, aluminium and smoked glass. It has had some upgrades for reliability (bigger resistors, for example) and the EL34s are matched Svetlanas. Here is a link to the upgrades- http://www.adrian-kingston.com/K4000.htm and the manual-
http://www.adrian-kingston.com/K4000.htm Mine has dual power supplies. The first 15w are Class A, and the bias is left as standard.
I am asking £300. I only have this picture at the moment, as it is in the loft and my broken collarbone hasn't healed enough for me to shift it for more photos. If there is serious interest I will get someone to move it for more photos. Oh, and posting it would be difficult, but I do have a 12mm MDF box I made for moving house, so I guess it would be possible.
