Sony Walkman WM-DD3
In this video I will repair SONY WM-DD3.
Part 1 - Mechanical.
1.1. Replacing the Main Gear. Usually produces a crackling sound.
1.2. Replacing the Rubber Ring, over time, the rubber ages and becomes hard,
which leads to poor contact between the engine and the flywheel,
which leads to uneven rotation of the flywheel, which leads to unstable
rotation of the magnetic tape in the cassette as well as sound distortion.
Part 2 - Replacement of all Aluminum Capacitors.
In aluminum capacitors, the electrolyte dries up and their capacitance drops
or does not work completely. Therefore, you need to replace 15 pieces
with new ones, you can buy from the link below GRA & AFCH Store.
