[Gonset] G-76 Question

[David Thompson]

I have a Gonset G-76 that works great thanks to K9STH on all bands.  However
it takes 130mv+ to read S9 on bands other than 80 and 40.  There is an
S-Meter Zero adjust on the rear but I looked thru the schematic and do not
see an S-Meter sensitivity adjustment.

I have the original Manual with several updates and a very long schematic
that is spliced together.

Is there a way to adjust the receiver section to S9 with 90mv as is the
usual standard?

Thanks  Dave K4JRB
