OKI 333B: A Full-Sized Reel Compact Tape Recorder.

OKI Electric Industry Co. Ltd., Meikosha, Tokyo, is a company with a rich history dating back to 1881. Originally a manufacturer of telephone and telegraph equipment, OKI ventured into the world of consumer electronics in the 1960s, producing computers and concurrently, audio tape recorders.

The model we delve into, the OKI 333B, was part of the four solid-state tape recorder lineup introduced in the USA in February 1965 by Chancellor Electronics Inc. With 17 transistors and a 4-track stereo unit, the OKI 333B offered a slim and attractive design suitable for any home or office setting.



One of the standout features of the OKI 333B is its versatility in placement, operating both vertically and horizontally with easy-to-use individual push-button controls. It weighs less than any other instrument of its kind, even a child could lift effortlessly as the weight is less than 7 kg. Such attention to design details makes it clear that OKI aimed for a product that not only delivered exceptional audio but also seamlessly integrated into various environments.

What truly sets the OKI 333B apart is its ability to create a mesmerizing sound experience across a broad spectrum. From the delicate whisper of a flute to the thunderous salvo of massed drums, this tape recorder demonstrated its prowess in handling diverse musical genres. In terms of specifications, the OKI 333B boasted a frequency response of 50 – 15,000 Hz, yielding the Revox G36 in the lower frequency range only (40 – 15,000 Hz). With 2 microphones and 2 radio-phono inputs, it catered to the needs of users with a variety of recording sources, adding to its overall versatility.

Another notable aspect is the recorder's economic advantage. Priced at only $229.95 in the USA, it offered a compelling alternative to the market-dominating Revox G36, which retailed at a significantly higher $500. This affordability, combined with custom testing for each unit and a 1-year guarantee, made the OKI 333B an attractive choice for audio enthusiasts seeking both quality and value.

Regarding OKI Electric, the business is still up and running. They manufacture a wide variety of electronic products, including Intelligent Transport Systems, Engineering Service Solutions, printers, and video servers. Regretfully, tape recorders are no longer made by them.
