A BASIC QUESTION

[Strat68]

I'm debugging a Derailer and I must be missing something obvious. Since the board and layout diagram identify parts by value how does one find a specific part on the board when there are multiples of a single value. I think I have an good idea due to proximity to other parts but I can't be certain. For example the schematic indicates a 1M resistor but there are 3 of them on the board.
Thanks

@Robert may be worth updating this build doc with a refdes pic

Thanks! I have isolated the problem (loud buzzing) to a section of the schematic, coming off pin 6, but want to make sure before I start replacing parts.

Oh wow, yeah that's an old one, I need to update that.

I'll try to get it updated today, in the meantime:
