Thanks for posting the schematics. Always interesting to study schematics to learn how circuits are done.

Could you please also take pictures of the PCB top & bottom. I would like to study how some of the section are done in PCB layout.
In particular is how they did the layout of the Log Amp.

I am away for 2 weeks and when I get back I will do that.

Thanks Kt, Clear photos.

There are two PCBs so no pic of the top of the LOG AMP & Meter drive and only half the main board.

I did find the Log amps circuit of the bottom (from pattern of the Dual matched NPNs). Traces are visible even though right in the center of the lighting glare.
