Backfeeder Layout

I need to troubleshoot a backfeeder but the illustrated board layout just labels the ICs by type (TL072) and not by number: IC1, IC2. This makes it almost impossible to trace the schematic on the actual board. Am I missing something obvious? This is an annoying thing about all the documents.
 
I sometimes use the shop pcb image where you can see most traces if I don't have the pcb then continuity check with my meter using the schematic

With this one being a big circuit I'd continuity check all TL072 pin 1's most connect to different value components aside from IC1 and 3 with a 22K so I'd then check something else to identify them e.g pin 7's or for example you can see IC3 has pins 3 and 6 connected

Something like this

Thanks everyone! I was able to find a board layout. It had gotten misplaced on my work bench. I'm sure I've got a short or bad solder joint somewhere. The only one I had found was the one on page 4 of the build doc. My mistake.
