The Black Lion Audio 500 Series B173 Preamplifier features the Cinemag input and Edcor output transformers. The +24V rail needed to power the B173 500 is converted from the +/- 16V rails of a 500 series rack using a custom DC-DC converter circuit specially designed to keep any unwanted noise or modulations out of the signal path. Complete isolation is then achieved through the use of inductors, ferrite beads, decoupling capacitors, power regulation, and a custom enclosure surrounding the entire circuit.

Cinemag input transformer
Edcor output transformer
