The AKAI RC-21 Wired Remote Control is a vintage unit specifically designed for reel-to-reel tape recorders, such as the GX-747, GX-77, and GX-646 models. Made in Japan by the renowned brand Akai, this remote control provides easy operation and control over your tape recorder. With a sleek design and precise functionality, the AKAI RC-21 is a must-have accessory for any vintage sound and vision enthusiast looking to enhance their collection. This genuine Akai RC-21 wired remote control was in my late father's collection. It is in a very worn state and would benefit from some restoration work. I haven't been able to test this unit. Comes from a pet and smoke free home.
