At long last I have found the time to devote to making a circuit published in Elektor Magazine in October 1977. I am sure most of you will have your own copies! The problem, simply put, are E300 JFETs still produced and if not, could anyone suggest a substitute? The circuit in question is an Impedance variation detector that I wish to use to make a kinetic sculpture. Thanking you in advance for any help that you can provide.
Steve.
E300 N-FET, HF, 25V, IDss>6mA, Up BF256B,C/BF348/BFT10A/2N5397
E310 N-FET, VHF, 25V, IDss>24mA, Up BFT10C/2SK125

** The E300 ( 25 volt, Nch jfet ) was made by Siliconix and appears to be obsolete.The 2N5486 has very similar specs and is readily available.

Thank you very much for your prompt reply. It is very much appreciated. Elektor, whilst being an excellent magazine, was in the early days especially, prone to revising their designs/component values in subsequent editions. None of which I have! Fingers crossed everything will work like a dream!
Cheers, Steve.
