U20109 Used JRC SE-3 Synchronous Detector MK-IV Version

The Sherwood Engineering SE-3 is a well-regarded outboard PLL synchronous detector designed to interface with the 455 kHz IF output of high-end HF receivers. It's a favorite upgrade for serious SWL and amateur operators looking to dramatically improve AM reception quality — reducing selective fading, improving audio clarity, and allowing sideband selection. This unit is from Sherwood Engineering Inc. and is labeled "high fidelity" on the front panel.
