Recently completed populating a dezbaz repro WG K6100 Input Protection PCB. When completed I noticed several of the resistors appeared to have the same color bands (markings), so I measured them and found the readings are confusing. For example, a resistor that should measure around 27K is measuring 8.8K, while the visually matching 1.2K resistor by it is measuring 0.9K. These are all blue base color resistors from Mouser and I believe the brand is KOA. While I need to check the manufacturer for the non-blue base (tan) 22K resistors, they are measuring 21.9K, which is well within tolerances.
I know these were installed correctly per the Mouser packaging, so is something in the circuit causing this or did Mouser get these mixed-up? I'm just confused on how two identically labeled resistors can have drastically different measurements (a little sure, due to tolerances, but more than 3 ohms, while being nowhere near their supposed rating)???
Ideas?
I'll post a good picture showing the repro IP PCB and resistors.
