Maxell - UD 35-90 / 7-Inch Tapes Bundle Reel to reel audio

The Maxell UD 35-90 (Ultra Dynamic) is one of the most famous and reliable 1/4" open-reel tape recorders in the history of vintage hi-fi, and this listing offers 9 of them, recorded only once with rock music (also Led Zeppelin) and still in their original boxes with the original adhesive labels.

As you can see from the photos the boxes are without writing and still have the original adhesive labels.
A really nice lot, hard to find in these excellent condition.

Why is it so sought after today?

Unlike many competing vintage tapes from the 1970s and 1980s (such as some Ampex or Scotch), the Maxell UD does not suffer from hydrolysis syndrome (Sticky Shed Syndrome).
The polyurethane binder used by Maxell has proven extremely stable over time: the tapes do not become sticky, do not squeak, and do not shed oxide onto the heads, making them safe to purchase even used or as stock footage (NOS - New Old Stock).

Please look carefully at the photos, which are an integral part of the description.

I guarantee fast, trackable, and insured shipping with sturdy and appropriate packaging, and, whenever possible, we will use recycled boxes in the interest of the environment.

Thank you for your attention.
