The second Beomaster 1900 unit is prepped for reassembly after completing the capacitor replacements and slider control repairs.

The Volume Control board was addressed first, requiring six capacitor replacements. Here’s the board before:

The Tone Control and FM Tuning board came next. While it only needed ten capacitors replaced, the Bass, Treble, and Balance sliders needed attention.
