Golden Age Project Pre-73Jr

The PRE-73 Jr is a one-channel vintage style microphone- and instrument preamplifier. The signal path uses only discrete components like resistors, capacitors and transistors. The in- and output is transformer balanced, using two different transformers, each one optimized for its purpose. This is the way audio components were built before integrated circuits became available.

Integrated circuits are small and cheap and widely used in most modern designs. It is clear though that audio components built with modern technology doesn´t always provide the best perceived sound quality or the type of character that the modern user desires.

On the contrary, the subjective sound quality delivered by vintage equipment is often prefered over the one delivered by modern units, a situation that is even more obvious now when music is recorded with cleansounding digital audio equipment.

This is the reason why so many vintage audio components are cloned and produced again and also why the vintage originals are often very expensive on the second hand market.

The circuit used in the PRE-73 Jr is similar to the preamp section in the classical 1073 module with a corresponding sound character that is warm, punchy, sweet and musical. These classic characteristics have been heard on countless recordings through the years and it is a versatile sound that works very well on most sound sources and in most genres.

The essence of this sound is now available at a surprisingly low cost, making it available to nearly everyone.
