A DESIGN THAT HAS BEEN 15 YEARS IN THE MAKING AND MORE THAN 50 YEARS OF HERITAGE
It’s no secret that we have been lovers of the 73 topology since the very beginning of Heritage Audio, especially the 3055-driven transformer coupled Class A output stage which is the trademark of that sound. After years of consideration, we’ve managed to adopt the legendary 3-transistor topology circuit to serve as the best DI you could ever get, at any price range.
This wasn’t an easy task, as a very high input impedance was needed and phantom powering was a must. The first transistor in the 73 stage was substituted by a J109 JFET, yielding a 2.2 megohm input impedance instead of the 47 Kohms in the original circuit. This transistor is the same one that is used (and loved) in the tens of thousands of the preamp DIs that Heritage Audio has included in all of its products over the last decade and a half turning it into an industry standard.
A clever design on the power supply section allows it to keep the metal can 2n3055 output transistor that directly drives the custom-developed silicon steel grain oriented output transformer, which is a phantom power friendly version of the venerable LO1166, custom built to enhance the natural performance of your instrument in the same, unique way, that a vintage 73 preamp will enhance a mic signal. The results need to be heard to be believed.
Being a transformer based unit, its output is isolated from the instrument and there is a further provision for l
