## Description

'73 Junior 500 Series Microphone Preamp. Following the success of the 1073/500 module, the '73 JR is a mic preamp in a single 500 series slot with some added features that will cover all the recording needs for engineers and musicians that don´t find the need to track with EQ. Employing only discrete circuitry and conventional components, the '73 junior is a faithful 3 stage all class A 1073 preamp. Styroflex and tantalum capacitors have been used throughout. No corners were cut. A useful all discrete class A hi pass filter has been added, essential for recording everything with the exception of probably kick drum and bass. The Line mode allows for reamping of prerecorded tracks and it´s perfect for adding some class A color to lifeless recordings. The smart switched DI (automatically switches from MIC to DI mode when inserting a MONO ¼" jack ) is an all discrete class A JFET circuit ahead of the MIC transformer, so all the juice is there. Finally, special care has been taken with power handling, implementing internal +24v slow turn on regulation (about 20 seconds to reach full voltage ).This makes your lunchbox PSU healthier and makes the 73JR independent of the rest of the slots.
