Golden Age Project Pre-73 Preamp

The PRE-73 is the first one-channel low-cost preamp on the market that is using a fully discrete signal path with three separate transformers for the balanced mic input, the line input and the output. The PRE-73 is perfect for almost any signal source, no matter if it's a microphone with a high or low sensitivity (like a passive ribbon mic), a synthesizer or sound module or an electric guitar or bass. The circuit is very similar to the classical preamp section of the Neve 1073 pre/EQ module with a corresponding sound character that is warm, punchy, sweet and musical. This classical sound has 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 PRE-73 has a maximum gain of 80 dB on the mic input and the gain range on the Line input is -20 to + 10dB. There is also a high-impedance instrument input. The input impedance of the microphone input can be switched between 300 and 1200 ohms, which makes it possible to affect the tone of most microphones. There is also phase switch and a simple 4-step LED signal level meter. The output level control makes it possible to make fine gain adjustments and also to overload the main gain stage for more character and then lower the signal to a suitable level before the output stage. Update: In very specific conditions (which are not necessarily how this preamp would normally be used), if the input and output volumes are both pegged and the DI is engaged after the volume levels have been set, the output signal takes on a pulse with a galloping sort of rhthym.
