A Little Inspiration｜Lexicon Prime Time Model 93 Digital Delay｜ Other Products

Superb 70s digital delay. In full working order - overhauled for us by a top engineer.
Great information about these units here on this page (including manuals etc).
In very good cosmetic condition with the wear on the face only showing around the edges. The top of the unit has some rack rash but nothing major. See photos for more information on cosmetic condition.
