Up for sale is an Brand New, Revive Audio Modified: Warm Audio WA73 preamp that sounds exceptional and comes with a full 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.

Modifications include a full circuit upgrade including all transistors, capacitors and many tweaks for the best possible performance that rivals the best designs and builds.

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.

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.

This includes an entire preamp and power supply section modification

We then pull all of the caps out the unit and replace them with long life, audio grade Panasonic/Nichicon 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 that is really pumped up on performance.

DescriptionWarm Audio WA73 1-Channel British Microphone PreampA Single Channel '73 For The Rest Of Us

If there’s one style of preamp that professional engineers would unanimously agree has defined the tone of pop/rock records for decades, it would most definitely be the venerable '73-style of mic pre. '73-style preamps have been massively used in recording and live applications for many years and are still considered to be the “Holy Grail” of preamp choices today. The Warm Audio “WA73 Family” consists of single and dual channel '73-style preamps (with & w/out EQ), that each pay careful homage to British audio history.

When we at Warm Audio decided to release the WA73 it was imperative that it met vintage expectation in both design and performance. The tone and sweet character that vintage '73-style mic preamps impart is so unique and familiar, that we had only the pure desire to release sonically accurate reproductions. After years of R&D, careful reverse-engineering, and countless hours of auditioning, the WA73 has been born.

The WA73 is a “Desert Island” boutique preamp, but it can also be classified as a studio and live work-horse. Classic '73-style preamps are known for being versatile tools that work with all kinds of microphones from Condenser, to Dynamic, to Ribbon. The WA73 equally shines on all types of microphones and sources including; vocals, acoustic/electric guitars, bass, drums, percussion, orchestras, keyboards, and even as a tone shaping tool to run partial or complete mixes through. With 80dB of gain and a fully discrete Carnhill Transformer balanced signal path, there’s no recording, mixing or engineering task that the WA73 can’t handle.

Hand Wired & Hand Assembled

Classic '73-style preamps were often hand-wired and so is the WA73!  Guru’s claim that a portion of the sought after classic British tone can be attributed to the hand-wired nature of the build.  The WA73 is hand-wired and hand assembled, including the pcb components that are all populated by hand.
