The Ghost in the Machine: Troubleshooting Intermittent Faults in Vintage Circuits

Author: Omid Farhang Published: January 1, 2026 Reading Time: 8 min

There is nothing more frustrating than a device that works perfectly until you try to show someone else. In the world of vintage electronics, these “intermittent faults” are the ultimate test of an engineer’s patience and methodology. Unlike a blown fuse or a charred resistor, an intermittent fault is a ghost. It might be a cold solder joint that only fails when the chassis expands from heat, or a silver-mica capacitor that only leaks under specific humidity levels. These are the problems that don’t show up on a static multimeter test. They require a dynamic, almost adversarial approach to troubleshooting. ...
