Introducing the Warm Audio WA73, the single-channel British mic preamplifier that accurately reproduces the legendary '73-style sound that has defined the tone of pop/rock records for decades. With 80dB of gain and a fully discrete Carnhill Transformer balanced signal path, the WA73 is a versatile tool that can handle any recording, mixing, or engineering task with ease. 

Now available in the Caribbean Trinidad. The WA73 is a boutique preamp that pays careful homage to British audio history. Warm Audio worked closely with Carnhill Transformers of Cambridgeshire, UK, to design faithful reproductions of the most coveted early version transformers used in classic '73-style British preamps. These transformers saturate sweetly when pushed and are known to make engineers cry when they hear how beautiful their mixes sound through them! 

The WA73 also maintains integrity to early British designs by using tantalum and polystyrene capacitors in the signal path and an output transistor choice that is much smoother in the high gain settings than what is typically found in modern '73-style preamps. And just like classic '73-style preamps, the WA73 is hand-wired and hand assembled, including the PCB components that are all populated by hand.  Whether you're recording vocals, acoustic/electric guitars, bass, drums, percussion, orchestras, keyboards, or running partial or complete mixes through it as a tone shaping tool, the WA73 can handle it all. It's the perfect choice for any studio or live work-horse, and it's the "Desert Island boutique preamp" that every engineer dreams of having in their arsenal. Get your hands on the Warm Audio WA73 and experience the true sound of British audio history!
