Modification of old Yamaha piezo preamp for Fishman pickup - help needed

[Mooly]

The TL072 is actually fairly similar to the model I have used. Both are fast 'audio grade' JFET devices. The TL062 is a low power version of the TL072 and has a reduced high frequncy performance (although still quite respectable in real terms).

Post #146 here shows how to use a '301 file' although like most things in LT, there are differnt ways of doing things.

See if the attached simulation runs OK.

So the only thing that remains to be done is finding an online store that sells the capacitor without charging a fortune for postage. We used to have an electronics store in town, but no more.Yours,Rob

I heard a rumor that DigiKey will sell with no postage charges if you order by MAIL rather than on line.

perhaps you can find an old radio or sowhat and solder out a cap with 27pF or 33pF........
