The design is a fully balanced, dual differential one. Probably the best Electrocompaniet power amp from their golden age. Resulting in Damping Factor of thousands. Will drive ANY speaker load, including highly inductive B&W Nautillus.
Preamp has a number of inputs and remote controller. No faults were present in either of these units and only cosmetic work has been done. Pre-amp had the volume pot cleaned as it started to crackle occasionally.
Very much in original condition. There are some minor marks on the front panels and a minor scratch here & there on top covers but not visible under normal circumstances.
Please see the last picture showing the AW-100DMB handles hidden inside the unit to match the look of the preamp (I have painted gold the screws which are normally hidden inside and put them on the outside, thus reversing the normal setup, as an option). #201 nano3 balanced cable (XLR). I have upgraded the connectors to the their most expensive, professional offering Neutrik EMS for "Broadcast & Live Recording". Like all Electrocompaniet amps from that era, these units too sounds just sublime. THE PRICE YOU GET WITH CALCULATOR IS FOR THE PRE-AMPLIFIER ONLY.
