1073 Classic Mic Pre 3 Band EQ

Mic Month Bundle with Heritage Audio 1073/500 Mic Preamp/EQ Module, and API 8-slot Lunchbox Bundle

Product Details
In case outboard fitting is preferred, the HA1073 can be installed into the Heritage Audio Frame 8 and Rack 2 powered enclosures. Special care has been taken in sourcing the correct components that ensure performance will be as close to a 1070s unit as it is possible nowadays. Custom polystyrene and polypropylene film tone capacitors have been developed to closely match the Siemens Styroflex and Mullard Mustard types of the late 60s and early 70s. Custom input transformers have also been co designed with Carnhill Transformers′ Oxford factory to our special requirements, which ensure correct harmonic distortion content and saturation points. The Heritage Audio 1073 is entirely handmade in our facilities in Spain, employing the same old-fashioned wiring and soldering techniques of the 70s. Manufacturing a single module takes several days of one of our master builders. All its circuitry is held into four plug-in cards.
