Posting here due to this being a very early PCB revision for the GFA-555. There is no silk screening on these. Back terminals instead of bright red/black are a reddish brown/black.
I picked up this amp from the original owner who claims it has never been touched.
I was using this "good" amp to help me reference and troubleshoot another I have, same early board.
The question is, there is what I assume to be R23 - 22.1k. on the right side, but on the left it is not installed. Amp works fine. Should I put it in there to match the right side?
Not sure if the later schematics I keep running into match this.

Update: so I did see a reference to this resistor on the schemos, but it is only for one side. I'm too much of a newb to know what the dotted lines around this area of the schematic indicates, could it be stating that it is for only one side and no r23 for the left side? ( bottom left)
Should I add this resistor to the right side as well?
