They sound great as they are, but with the addition of the classic UK made Carnhill transformers across the mic input and output, they sound even truer to the originals with a fuller more robust tonal presentation, particularly across the mid and low mids bands

 

 

I compared it with the original Alctron version using a vocal & the lower frequencies were more open
It is in the original box with external power, 230 volts AC to 24 VacIntroduction:The MP73EQ is a high-end Microphone Preamplifier and Equalizer, its power starts with its input stage, which allows you to select the perfect impedance for your microphone. This function alone makes the MP73EQ invaluable to any serious engineer, because it allows you to get a wide range of tone out of a single microphone.It also lets you get the most out of ribbons and other low-output” microphones.
