I’m selling a Heritage Audio 73 JR Mk1 Series 500 microphone and line preamp. A high-end classic based on the British Neve 1073 Class A circuit. It works perfectly. It features original Carnhill transformers on both the input and output, which provide that body, bass weight, and harmonic richness so characteristic of the classic analog sound. To me, it sounds better than the Mk2. Gain up to +80 dB, discrete high-pass filter (HPF), -20 dB PAD attenuator, and phase switch. For use exclusively in smoke-free studios. Gain, LOZ, PAD, and PHASE controls. Front-panel DI connection.
