Product Description: This is Sony's top-of-the-line open reel tape, "SLH-550." I am selling it as I organize my parents' house. • Model: SLH-550 (Super Low-Noise Hi-Output) • Specifications: 7-inch reel / Length 550m / Thickness 36 microns • Condition: The outer box has slight scratches due to aging, but it is generally in beautiful condition. Accessories such as the instruction manual and cleaning sheet are also included. • Operation: I do not currently have recording equipment, so I have not been able to confirm playback. The tape looks to be in good condition without mold or stickiness, but please understand that it is an old magnetic tape before purchasing. How about it for those who love vintage audio, for collection or recording? Instant purchase is OK. I will pack it carefully and ship it.
