The OA90 is a classic, vintage-style Germanium diode that has been used in countless audio circuits over the decades. It possesses a unique sonic signature that audiophiles have come to love.
The OA90 is a low voltage rectifier diode that provides a quick and efficient response time. It is able to handle a maximum current of 15mA and can withstand a maximum reverse voltage of 30V. Its small size and versatile nature make it an ideal choice for use in a wide range of circuit designs, including guitar pedals, amplifiers, and other audio gear.
One of the key features of the OA90 is its distinctive sound quality. Because it is made from Germanium, it produces a warm and rich tone that is hard to replicate with other materials. Germanium diodes are known for their asymmetrical clipping characteristics, which produce a more natural and organic sound compared to Silicon diodes.
This makes the OA90 an excellent choice for guitar pedals, where musicality and tonal character are highly valued. When used in a distortion or overdrive pedal, the OA90 can provide a sweet, singing sustain that many guitarists crave.
In addition to its musical characteristics, the OA90 is also a highly reliable and durable diode. It features a rugged glass construction that can withstand the rigors of daily use.
Overall, the OA90 is an excellent choice for anyone looking to add some vintage charm to their audio circuit designs. With its unique sound quality and reliable performance, it is a favorite among audiophiles and musicians alike.
