AC Delco made many variants of this stereo for both Chevrolet and GM cars, trucks, and vans from the early 80&rsquo;s to the mid-90&rsquo;s. While many of the stereos have more or less features (cassette players, radio presets, etc), the amplifier section of the radio is fairly standard and unchanged.</p> <h2 id="internal-pinout-and-schematic">Internal Pinout and Schematic</h2> <p><a href="delco-stereo-11.jpg"><img alt="delco stereo 11" loading="lazy" src="https://pcbisolation.com/blog/repairing-and-adding-bluetooth-to-a-90s-delco-radio/delco-stereo-11.jpg"></a></p>
