Johnson Challenger with a shorted capacitor. Made a mess. Tracing down the fault was pretty easy. Just follow the smoke trail! The Challenger was a unique rig. The finals and driver tubes are 6DQ6A's. Sweep tubes normally seen in CB Linear amplifiers. This is a real power house and sounds decent on AM. Just a quick project to show you the damage.
