Employing discrete circuitry and conventional components, the 73JR II is a faithful 3 stage all Class-A 73 preamp. Styroflex and tantalum capacitors have been used throughout. No corners were cut.The all-discrete Class-A hi-pass filter is sweepable from 20 to 220 Hz — making it easier to make your low end tighter without affecting desired frequencies.The Line mode allows for reamping of prerecorded tracks, and is a perfect solution for adding some color to lifeless recordings. The DI input (which automatically switches to DI mode when inserting a ¼” TS cable) is an all-discrete Class-A JFET circuit in front of the microphone transformer — giving you all of the color and weight you could ask for.Finally, special care has been taken with power handling, implementing internal +24v slow-turn-on-regulation. This is extremely healthy for your 500 series enclosure’s power supply, and keeps the 73JR II’s power independant from other slots.
Heritage quality, through and through.
There are
several compromises usually made when adapting a 73 preamp for the 500
Series, but none that you will find in the 73JR II. The 73JR II uses the
full 3 gain stage circuit for up to 80 dB of gain with noise of -125dBu
EIN all over the gain positions. The 73JR II uses a true 24volt on
board power supply for identical performace and distortion point.The
73JR II uses only discrete, through hole traditional components and hand
labor for that great 70s vibe.The output transformer is a custom
Carnhill, made for in the St Ives factory. The input transformer is a
custom Carnhill, made in Carnhill ́s Oxford factory — this one has a
huge impact on the extra mojo of the unit, and is the same one found in
our higher-end 80 Series modules
