Beomaster 2400: Finished the capacitor replacement

The last two boards to replace capacitors on are the Volume Control and Tone Control/Tuning boards.
Before starting those however I finished up work on the main board by replacing the left and right channel trimmer resistors for the no-load current adjustment (which will be performed later).

Here are the left and right trimmer resistors for no-load current adjustment on the Beomaster 2400 output amplifier.

I like using multi-turn trimmers for the no-load current (or idle current) adjustment. They make fine adjustments much easier.  Here are the new, Bourns 250Ω trimmers next to the original trimmers.

Here are the new trimmers installed on the main board.

The small adjustment screw is also easier to get to for the adjustment procedure once the Beomaster is put back together.

Moving on...here is the Beomaster 2400 Volume Control board recap before and after pictures. There were six tantalum capacitors on that board that I replaced with WIMA MKS capacitors.

Last is the Tone Control and FM Tuning board.

As I saw on the main board, all of the electrolytic capacitors were either way out of tolerance or close to the tolerance limit. Here are some samples of the measurements I made of the old capacitors from this Beomaster.

The next tasks of this Beomaster restoration will be to check and repair the Bass, Treble and Balance slider controls.
