I know, it is the one in the link I posted. But, how can I identify the
resistors? There's written nothing on the PCB... I downloaded a schematic
and I think I have found the right resistors but they are connected
differently to the AN6562: could it be because my PCB is the NP-090B while
the schematic refers to the NP-090?
My NP-090B PCB uses two AN6562 op. amp. and a 74LS14.
