If there is one preamp - equalizer that professional sound engineers would unanimously agree has defined the sound of pop/rock records for the past 50+ years, it would undoubtedly be the 1073. The 1073 has been widely used in recordings and live applications for decades and is still considered the "Holy Grail" of preamps (eq's) today.

With 80dB gain, as well as a signal path from discrete Carnhill Transformer circuitry and a versatile three-band parametric EQ (in the WA73-EQ and WA273-EQ products), there are no recordings or mixes that the WA73, WA73-EQ, WA273, and WA273-EQ cannot handle.

• Hand-wired and assembled. The entire range of WA73 preamps (eq’s) is hand assembled and wired.
• CARNHILL TRANSFORMERS MADE IN THE UK. The Marinain Radar transformers are regarded as the most desirable choice for 1073.
• UK Blore Edwards Switch-Pots (WA73-EQ & WA273-EQ). The use of Blore-Edwards potentiometer materials further indicates the quality of Warm Audio’s preamps and eqs.
