Hi J_P.
The "experimental LRL made by Andreas, showing his Dillinger pistol with a high voltage Tesla coil" is not a design from Andreas. It is a commercial lrl with name Positron, Andreas the only that he made is to reverse the schematic, nothing else.
Now about Cryfton... it is a Andy Flind MFD. About mini Cryfton... i don't know but this time i really want to see a real lrl
