stuckinhere Posted November 8, 2020 Posted November 8, 2020 Further information: Single (One/1) Musical Fidelity 550K Supercharger for sale. This amp was given to me approx six months ago to repay a debt. It had been sitting in a dark corner of a storage container for some years. When it was given to me both speaker connections were broken off and the base plate was showing signs of surface rust. I took about restoring the amplifier with the idea of using it with a passive subwoofer or to run a centre speaker (total overkill but think of the headroom..). The internals are in pristine condition. The external case of the amp is in fair/average condition. Both speaker connection have been replaced and the base plate has had all rust removed and given a fresh coat of automotive paint. I have tested the amplifier and it sounds better than I have the ability to describe (numerous reviews online and GIYF).
