Thanks to RadioShackCatalogs.com I found my parents’ Realistic receiver on page 24 of the 1973 Radio Shack catalog. It was $129.95 with a “$24.95 value” Walnut Wood Case, color-changing dial pointer, tape monitor switch, and four-way mode selector. 25-watts in stereo! I ended up with this receiver after they got a new one, and I used it through college and several years afterwards. The on/off + volume switch got flaky and my brother altered it to have a separate on/off toggle and volume knob. I think I still have it somewhere. (via MeFi)
