Beomaster 2400 Type 2902: Recapping the tone control board and FM tuner

To wrap up the capacitor replacement on this Beomaster 2400 restoration there is just one capacitor in the FM tuner box and a handful of capacitors on the tone control board.

The FM tuner box has top and bottom lids that must be removed. There is a shield wire that must be desoldered from the bottom lid before it can be opened. The bottom lid is necessary to desolder the lone 10uF capacitor leads.



















Under the top lid we can find the capacitor that will be replaced.

The last board to recap is the control board for the tone controls and FM tuning. There are just ten capacitors to replace.  Here is the before and after picture.






























I am not finished with this tone control board yet. The next task is to remove the Bass, Treble and Balance slide control devices to rebuild them.
