Jaycar 27K Ohm 0.5W Metal Film Resistor – ER0606

That circuit diagram doesn't say 'close enough.' It says 27K, and your build needs it to actually be 27K. This Jaycar metal film resistor delivers that exact value at a 0.5-watt rating. Metal film means less drift as the part heats up, so the gain stage or voltage divider you're wiring doesn't wander after ten minutes of runtime. One small part, one less thing stopping you from closing the lid on the project
