Hi all

I'm building a pair of F4 amps and just ordered boards from DIYaudio store. I'm wondering if there is an alternative part for the input jfets (2Sk170, 2Sj74) as they seem to be in scarce supply. (I notice that they are not available in pairs on the site.)

I have been warned against ordering knock-off parts (ebay) as quality may not be guaranteed.

Is there an alternate part that would work for the F4 without compromising significantly on the original design? Something I could find at Mouser or Digikey, etc? Has anyone tried alternate parts with good results?
