We have two of these units, the other has been fully upgraded and serviced by ARC. If that unit is out of your price range this might be the answer.
Many consider the SP3 as the best preamp ARC ever produced.
Its classic looks and reliable operation has made this piece a favorite among classic collectors.
This particular sample came from a collector that didn’t use it very much. It mostly sat on a shelf looking pretty.
Cosmetic condition is very good for an SP3. The top cover is free from rust, the knobs and faceplate are near perfect and the silk screening is intact.
