Here's something that I will do. I will send one of my working preamps by mail and at no cost to the person who needs one of these. How about that? Len in the Toronto area.
 
If 20db boost is OK then this is for you.

If you build this circuit I would really appreciate it if you would let all of us know the results that you get. I have built two and they work perfectly. You must use the fet transistors specified for the lowest noise. I have read that the gain is from 20-25db. Len.
[email protected] Thanks so much for this schematic.! Question- would it be better to put the 10p caps right on the jack itself for RF? I've seem tnis done with "pimped Alice" mods where it was suggested that they work best close to the jack. Also. where did you insert your blue LED? You said you used acouple of 1Mohm resistrs with that, and the LED had to be blue. can you elaborate? Thanks so much. Cheers
