Compatible transitor to replace mpf 102?

[ppatchmods]

I'm doing a mosfet mod on an sd-1 and it calls for mpf 102's and I can't find anything locally.  Is there a compatible transitor I can try? thanks

Hi
MPF102 is a JFET.  Are you after a JFET or a MOSFET?  The MPF102 is similar to the 2N5457 and 2N5458.
If you want a MOSFET, try the 2N7000 or BS170.
cheers

Thanks for the info.  It is for a mosfet mod, but it calls for the jfet.  I'll try those.

You could use a J201, but they don't have as much gain as the others, however I have never noticed that much of a difference.

I believe the J201 has MORE gain than the others mentioned.

  MPF102 low gain
  2n5457 
  J201  high gain
  NTE458  higher gain
  Higher gain can sound too 'stiff'...there' goes the adverb, but high gain can sound 'stiff'.

the DIY Faq has compatible FETs listed.
