Title: Solo Isolate on later 4000 G+ not in schematics
Post by: RoyMixer on April 01, 2018, 05:29:27 PM

Does anyone understand the circuit from the solo isolate switch on the group trim pot?

I am trying to add this functionality to my 8K GB.   I don't any reference to it in any service manual. On a standard 4K G+, I can see  that switch goes to D5  (plus lead with D5 removed) on the 611 motherboard. this makes recall work for that switch.  but there is more to this and I am looking for how it works.

I have attached a document kindly supplied by brewery .

Thanks!!

Roy

Just realizing that I forgot the RM26 to 10 pin IDC. connector on logic card. (not obvious on logic schematic)

that was it.
