Here is an example of the restoration of a Rönisch Hupfeld Tri-Phonola upright. Overall the piano was very well preserved in its original state, but the pump cabinet was missing. Due to aging, the Tri-Phonola mechanism had stopped working. As part of the work, we completely restored the Hupfeld Tri-Phonola mechanism, built a new pump cabinet using original components and repolished the finish in shellac.
The Tri-Phonola now plays again in all its different modes – as a hand-played piano, as a pedal-operated expression or reproducing instrument, as an electrically driven reproducing piano and also as an electrically driven expression piano. Today this rare instrument is in private ownership in the Munich area.
