SONOSTALGIE: Loewe Opta Tempo 92005 upgrade with Symfonisk by Matthias_Thullner

Last crawled date: 3 years ago

Upgraded my dad's old radio Loewe Opta Tempo 92005 with an Ikea Symfonisk (SONOS compatible) speaker. Symfonisk hack.
removed the old speaker chassis and elektronics
needed to squeeze the speaker chassis and the bass-reflex-tube into the Loewe radio box.
mounting for speaker chassis and bass-reflex-tube made out of wood
the receiver dials and volume potentiometer board was covered with a self printed plastic cover
the back cover was doubled with another wooden plate
the box is not really accustically closed, the back cover has some small open vents (would be better to close them)
the front plastic cover of receiver dials is loose and creates some disturbence sounds at high volumes
the whole thing was inspired by https://makezine.com/2019/08/16/hacking-the-sonos-ikea-symfonisk-into-a-high-quality-speaker-amp/
