Beomaster 2400: Restoration Project for a Texas Owner

There is just barely enough time to get in one more vintage Bang & Olufsen restoration project for 2019.

This is another Beomaster 2400 restoration. I have had quite a few Beomaster 1900 and 2400 projects this year so why not another one.

Let's jump right in and evaluate the starting condition of this Beomaster.

Cosmetically it looks very nice.

Since it is in such nice shape I decided to power this unit up and see what its status is with regard to lights and touch control switches.

I was pleasantly surprised that all of the touch switches work and most of the lights do as well. The Treble indicator light is burned out apparently.

Now on to opening the Beomaster 2400 cabinet up to get to the circuit boards inside.
For this restoration project I will be doing the usual replacement of electrolytic & tantalum capacitors, the cleaning of the slider switches and any other repairs I run into as I check out the insides of this receiver.

First I remove the door and panel for the tone controls and FM channel tuning.

Second is the removal of the Beomaster 2400 bottom plate.

Note that the Phono DIN plug is the 7-pin type. That means this Beomaster has (or supports) the circuitry for (wired) remote control of a Beogram 4004.
That is desirable in this case because the owner has a fully restored Beogram 4004 ready to use with this receiver.

Now for the removal of the touch control panel.

The bass, treble and balance controls have indicator masks that are in excellent condition. I will have to look closer but all three slider controls appear to be fully intact.

This version of a Beomaster 2400 has different and newer board to board connectors.

Here is the main body of the Beomaster 2400 after I have removed all of the other components.

I don't like trying to de-solder and solder electrical components in between the frame pieces of the cabinet. I prefer to remove boards and components from a unit and work on them individually.
This Beomaster 2400 is now broken down to where I can start recapping the main board.
I like to start with the most difficult task first and get it out of the way.
