The first consumer reel-to-reel tape player from KLH, and the first consumer product with Dolby Noise Reduction.
Overview
The KLH Model Forty is the first consumer reel-to-reel tape player KLH made. It is also the first consumer audio product to include Dolby Noise Reduction. It is described as a pioneering consumer reel-to-reel. KLH built only about 12,000 units over four years of production. Don't confuse it with the later KLH Model Forty-One.

Context
The Model Forty was the first consumer product with Dolby Noise Reduction, which set it apart in the early high-fidelity market. About 12,000 units were made during its four-year production run.
Market
One contemporary review gave the price as $600 (approximately £250 at the time) and called it good value. Today it is described as "Incredibly Rare." Collectors report trouble finding replacement parts, such as the 1/4 inch capstan.
