The "Beatle Preamp"
Source: John Hinson, Revolution Recording Equipment - California, USA.
Reproduction of the original REDD.47 mic preamp that was utilized at Abbey Road EMI Studios during the mid to late 60's.
"...The REDD.47 was a wonderful sounding amplifier and was by far the most-used mic amp on Beatles sessions, being called upon for essentially every Beatles track recorded after 1963. It was certainly responsible for some of the unique character of the 1964-1968 Beatles recordings, particularly in the edgy treble regions."

This reproduction follows the original REDD.47 EMI circuit featuring EF86 and E88CC valves, with integrated power supply (super-filtered and regulated) and additional outboard REDD.51 desk componentry consisting of bass-lift, phantom, attenuation, 10dB pad and phase.
