Panasonic CH-72
Surviving information on the Panasonic CH-72 is thin. The model appears in HI-Fi-Stereo-Buyers for both 1973 and 1975, so it was at least offered during the early-to-mid '70s. The scans are fragmentary, and the CH-72's own spec line didn't come through the OCR cleanly.
The 1973 page (p.108) groups it with a component that had a mike input with mixer, dimensions around 17⅞ × 6¾ × 16⅛ inches, and a $429.95 price. An SA-6800X is listed next to it at $299.50. The 1975 page (p.105) places it among four-channel receivers. A nearby entry gives roughly 17 W/ch continuous RMS at 0.8% THD, FM sensitivity around 2 µV, a walnut veneer cabinet with extruded aluminum control panel, and a $499.95 price. The OCR doesn't tie those lines to the CH-72 for certain, so treat them as neighborhood context, not verified specs.
It's a Panasonic audio component from the four-channel era, and it's still mostly undocumented.
