You've got the breadboard half-done and the one missing value is 39K. The big-box store doesn't carry it loose, and the online marketplace wants four weeks for a single unit. These eight 39K ohm, 0.5-watt metal film resistors are Jaycar's standard part. They match the size of the 1/4W carbon film resistors already in your parts tray, so no layout changes, no re-tinning. Solder them in, power up, done
