Elektor published a schematic many, many years ago :)

You should try a power PHEMT instead of all those jfets. Some parts have Idss of a couple of amps, and the transconductance is amazing, measured in Siemens, not mS.

I used to read that magazine, called 'Elektuur' here, long time ago. Had some funny projects, and I used some of their ideas in my job too. Does it still exist? Internet is so much a better resource these days, and free.

It's still there though the name of the Dutch version has been changed to "Elektor" some four years ago. Last thing I made was "Coil clinic" as I was interested in measuring coils at the time. But IMHO it was a typical one off design. Better and cheaper designs on the internet although they also are not very accurate. Learned me the truth about the saying that you should measure coils at the frequency you want to use them.
