Up for sale is a Revive Audio Modified: Golden Age Pre-573 Mk2 Mic preamp that sounds excellent and is new in the box only opened for modification.
We all know these preamps pack a good price to performance ratio but with the modifications they simply sound excellent with better bandwidth, higher headroom and sound less muddy to boot.
The character smooths out and the noise floor is lowered to a point where the audio is just right and a lot closer to the original Neve Design minus the Carnhill transforms (ask us about this upgrade as well:)
What we do to these little boxes is essentially gut the insides.
We pull all of the transistors out and replace them with high HFE transistors for better bandwidth and lower noise to more closely resemble the original Neve design.
We then pull all of the caps out the unit and replace them with long life, audio grade Panasonic capacitors for even lower noise and better musicality.
The power supply is then upgraded for longer life, lower noise and better filtration of noise as the icing on the cake.
We walk away with a wonderful sounding preamp with modifications that we receive nothing but positive feedback about:)
Here is some more info on the stock design:
The Golden Age Pre-573 MKII is a refreshing update, with a lower noise floor and greater dynamic range. The 500-Series Pre-73 MKII provides a low cost alternative to microphone pre-amplification featuring a fully discrete signal path by utilizing separate transformers for the balanced mic input, the line input and the output. Similar to the circuit you would find in the Neve 1073 preamp/EQ with a remarkably similar output.
The versatile sound of the Golden Age Pre-573 MKII works incredibly with most sound sources and in most genres. The Golden Age Project Pre-573 MKII has a maximum gain of 80 dB on the mic input and the gain range on the Line input is -20 to + 10 dB.Made for 500-Series racks
