In the component list L1 is 330uH.
I bought the kit and L1 is actually 680uH.
Does somebody know what is the correct value ?

thanks

Elektor Labs confirm that the 680uH coil included in the kit can be used without problems. In tems of effective inductance and reactance at the frequencies involved, it comes close to the operation of the 330uH type originally designed into the circuit.
