INTRODUCTION
Thank you for purchasing Sound Scourge equipment. The equipment you now own is a result of
many hours of research and development as well as multiple recording and playback tests.
The NV73p preamplifier is a transistor device with a signal path based solely on discrete elements.
The preamplifier has a transformer balanced microphone input with a high impedance instrumental
input. The preamplifier’s signal output is transformer balanced as well. All the preamp blocks
work in class A.
We have taken a rigorous approach to both components and sound of the preamplifier. The device
is manually assembled from selected parts characterized by a narrow parameter tolerance.
The signal path has been reduced to its minimal length and the signal is guided through top class
rotary switches. Switching impedance, signal phase, etc. is accomplished by hermetically sealed
signal relays.
Nv73p casing is made of anodized aluminum and all elements are machined with high accuracy.
