If you mean the Andy Flind then you must search at forum.
Esteban made some modifications and make it a good lrl (as he was telling).
The good is that you can construct the schematic as is (on original pcb) and later to make the mods and maybe the adds. In place of T1 you can use a tuned coil.
With little mods on it there is a very expensive lrl (don't ask me if it works
)
