Revive Audio Pre73 Modification Service:
Simply place your order here to purchase your Modification Service for your existing Pre73Mk2, Mk1, Mk3, or 573 preamp.
This is by far the most comprehensive modification being offered on the market. Hands down!
Some companies replace a handful of parts at the major bottle necks where we modify and adjust the entire circuit.
For customers that inquire, the Circuit modification will yield much higher performance results from the circuit than the transformer upgrade and is a better value.
Transformer upgrades do give the unit the authentic character of the Neve design but do not increase headroom or frequency response by very much.
Carnhill Transformer upgrade options as well as authentic knob upgrades are also available for those that want the ultimate Neve Machine!
Once your payment is complete a Work Order# and Mail-in instructions to send in your unit.
This is your complete payment for your modification Service and includes Free Return shipping back to your door.
About the Modifications:
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 smoothes 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.
