JAYCAR 3.9 MΩ 0.25W Carbon Film Resistor (ER1662)

That 3.9 megaohm slot in your design isn't interchangeable with a 4.7 or a 2.7 — and you know it. This JAYCAR carbon film resistor is the exact value your circuit needs, rated at 0.25 watts for continuous duty. Carbon film construction keeps drift low over time, so the reading you set up today still holds next month. One component, correct spec, no compromise. Slot it in and close that ticket
