This amplifier was acquired new with plans to power a large JBL theater system that never materialized.

We received this NEW in its originally sealed box, box which we opened to confirm the contents. 

Complete like the day it left the factory. Also includes the rack ears as show in in our photos.

It came with another 5 channel version that you can view on our store by clicking here.

Retail was $2495 when originally produced.

*Note the first photo and last three photos in this listing are from Google for this exact model - they are not photos of this New in Box/New Old Stock amplifier which is likely in even better condition since it's never been used.

Great review here with all possible details.

Sherbourn 7/2100A Owner's Manual

The 7/2100A weighs an astounding 115 pounds and features the world’s first seven mono block, seven toroidal transformer amplifier.

This brute will output a massive 2.1 kW and comes with two power cords to ensure that you can pull all of the needed power from two outlets, which eliminates the need to install a special 20-amp circuit.

Sherbourn uses only the finest components, including fifty-six bi-polar Mosfet transistors and has an over 150,000 microfarad capacitance.

The rear panel includes XLR and RCA inputs, gold plated five-way binding posts and a low voltage trigger input.

Unique to Sherbourn is our LDS, (Load Detection System) that allows the amp to sample the signal before powering up and will detect if the “load” is within safe parameters.

200 x 7 @ 8 OHMS (All Channels Driven)
300 x 7 @ 4 OHMS (All Channels Driven)

Six of the Seven channels can be bridged to give a front stage output of 400 x 3 @ 8 OHMS and 600 x 3 @ 4 OHMS
