Some years after the rebuild it was thought that the Willis changes, though well intentioned, detracted too much from the original concept, so it was decided to restore the instrument to the Lewis specifications. The Durham-based firm of Harrison and Harrison was engaged, and the work was carried out in two stages. In 1986, the electrics were renewed, and although the Willis console was retained, it was given a solid state action with eight memory levels for the combination pistons and four for the Crescendo pedal. Also, the Willis swell pedals were replaced by balanced pedals.
