This is an authentic Panasonic RQ-4350 4-band stereo cassette recorder boombox manufactured by Matsushita Electric Industrial Co., Ltd. in Japan around 1978. Highly regarded by collectors for its heavy-duty construction and "Stereo Mac ST-7" styling, this boombox features a distinct top-loading mechanical control matrix with metallic toggle switches. It operates across multiple voltage configurations (AC 90-250V) or via six 1.5V D-cell batteries. The faceplate boasts independent analog VU signal needle meters, fine-tuned bass/treble slider pots, dual built-in condenser microphones, and a massive multi-section chrome telescopic antenna.
