One of the ways to find a persistent short is to start immediately after the resistor that is getting warm, with the schematic beside you, then follow and disconnect one wire, one component at a time, followed by a test each time. If nothing changes, reconnect the wire or component and go to another branch of wiring. If the resistor stops overheating, keep following that particular path. Don't skip any wire or component. Just disconnect, test, reconnect until you find the short.
