Up for sale is a Revive Audio Modified: Golden Age Pre73 Mk3 Plus version Mic preamp that sounds excellent, comes loaded with transformers and is new in the box only opened for modification.
1 year warranty, 

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 then install Bakelite Neve Style knobs. 

We walk away with a wonderful sounding preamp with modifications that we receive nothing but positive feedback about:)

Product Description

The PRE-73 MKIII is a one-channel vintage style microphone-, line- and instrument preamplifier. The signal path uses only discrete components like resistors, capacitors and transistors. The in- and output is transformer balanced, using two different transformers, each one optimized for its purpose. This is the way audio components were built before integrated circuits became available.

The circuit used in the PRE-73 MKIII is similar to the preamp section in the classical 1073 module with a corresponding sound character that is warm, punchy, sweet and musical. These classic characteristics have 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 essence of this sound is now available at a surprisingly low cost, making it available to nearly everyone.

The MKIII has the following new features compared to the MKII:

Tantalum capacitors in the signal path.
Selectable two position high frequency AIR boost eq, 3 or 6 dB @ 30 kHz.
Selectable two frequency high pass filter, 6 dB/octave at 40 or 170Hz.
The pcb is prepared for the Carnhill input transformer.
Revised and less complicated GAIN switch with a separate switch for MIC/LINE selection.
All GAIN settings can also be used in LINE mode
