Try these that I found through Google.

www DOT qsl DOT net/kk5dr/micamp.html
www DOT elecraft DOT com/Apps/microphone_pre.htm

The one on the Elecraft page would need a
DC blocking capacitor on the output from Q1
collector.

The Heil HMP schematic is nothing new. I did get the
schematic from one of the Icom Hamshack pages from
QSL.net. I do own a Heil HMP which went bad and did
compare the schematic to the finished unit. I was able
to repair my unit as the FET was faulty.

I do not have a url to the page as I did check my
printed copy.

If I do find it I will post it out here.
