This made in 1979 Nak 680ZX is truly masterpiece by design and implementation. Worldwide voltage switch. You can use it anywhere in the world if so desired. Taken apart, suspicious parts replaced. All rubber parts replaced. Cleaned, lubed, dialed in by factory service manual to perfection. It plays and records amazingly well for cassette deck. Will outperform reel to reels in most cases. Even at half speed on good tape. I also replaced all lights with original incandescent bulbs. There absolutely zero signs of use on case and heads. Rack mountable with optional mounts that is included. I was restoring it for myself. I’m retired electronic engineer on a mission to save great electronics of the past for future generations to enjoy. Check”more ads by this user” for more vintage electronics. Local sale only.
