About This Listing

This is a unique, one-off opportunity to own an incredibly rare piece of vintage outboard. This A&D F600-RS is possibly one of the most sought after pieces of studio equipment ever made.

The module version of the F600 was installed in several Helios desks and was used on countless classic recordings. The Rolling Stones Mobile Helios console had both F600's and 700's installed and the second Helios console built for Olympic Studios had F600's installed.  You can read about the F600 being used for Led Zeppelin's 'When the Levee Breaks' here:

"In many ways the sound of that album has become the bench mark for rock music and the drum sound, highlighted on the track 'When the Levee Breaks' must rate as one of the best if not 'the' best rock sound ever captured... John Bonham had just received a new drum kit from the Ludwig factory. He was keen to try it out but the recording room was being used for guitars so a roadie set the kit up at the bottom of the Stairwell in the large entrance hall of the house.

On hearing this, engineer Andy Johns realised that they had something special here. This was the place to record Bonham. Two Beyerdynamic M160 microphones were hung down the stairwell from the second floor, fed out into the mobile's Helios desk and heavily compressed with an Audio and Design F600 Compressor. Echo was then added from Jimmy Page's Binson echo unit."

I've just had this unit serviced for sale. The work included:

A full recap of both preamp boards / Replacement of four bantam jacks with (insulated) stereo 1/4" jacks / Rewiring of all jack to board connections / Full set-up calibration.

A very rare opportunity. Payment preferably by bank transfer unless Paypal fees covered.
