[Icom] SM-20

[David Hammond]

Hi Everyone,

I am looking for a schematic for the  Icom SM-20 microphone amplifier
circuit.  The standard SM-20 User Manual (a single sheet enclosed with the
microphone) does not include a schematic drawing.

Anyone have one to share or source?

The list earlier last month was to a source for the manual with no schematic
as I recall.

I find my SM-20 and IC756Pro II to be the almost perfect SSB match up. Would
like to try to homebrew the mic amp circuit for use with my homemade
electret
condenser mic headset.

Thanks for any help in advance.
