"Carnhill" Class A mic/line amp/EQ in API 500 series format, derived from the legendary Neve 1073

The Audio Maintenance ez1073-500 is a mono, Class A, mic pre-amp, line amp and EQ/Filter module inspired by original 1073 units. It comes in dual-slot  500 Series format.

Fully populated with Carnhill transformers and inductors to achieve its distinctive classic sound, this high-end hand-built British module  offers exceptional quality and a great sounding preamp and EQ for your 500 Series rack. Not surprising when you consider that it is derived from the legendary Neve 1073, but surprising when you read the comments by users that rate it alongside the original units.

...we found the ez1073-500 to be indistinguishable from our Neve 1070Ls. It was far closer in sound than even our Neve 1064s, which was a shock to say the least.

...I would definitely recommend this piece to anyone in the market for a Neve clone. I shouldn't even call it a clone. This thing is real!
