The restoration continues! Today, I replaced the remaining electrolytic capacitors on my Beocord 5000 (4715/4716). New electrolytics bring peace of mind!

The power supply board, including its reservoir and AC motor capacitors, along with the motor control, electronic switch, and operational control boards, were all addressed:

The Motor Control board, responsible for the take-up motor, had only one Tantalum capacitor that needed replacement:

Here it is after the replacement:

Next is the Electronic Switch board. This board manages the keyboard, counter, and tape transport monitor. A before picture:

Moving on to the Operational Control PCB. Before:

And after:

The following picture shows the two recording volume sliders located under the Operational Control board. This is a great example of 1970s B&O design. It’s essentially an analog representation of what we now achieve with digital sliders on touchscreens. The two red strips are housed within a white, illuminated compartment beneath a plexiglass cover. This creates the illusion of a linear indicator that transitions smoothly from white to red as the volume increases. The potentiometer controls on the Operational Control board, responsible for actual recording volume adjustment, are driven by the toothed racks:

Finally, we have the power supply. There’s just a single electrolytic capacitor directly on the board. Before:

And after:

The power supply utilizes several external reservoir capacitors. This is the 1 uF capacitor on the +12V regulator before replacement:

And after:

Here we see the power supply’s primary reservoir capacitors and the AC motor cap before replacement:

And after. Two smaller, back-to-back 33uF polar capacitors have replaced the original 16uF bipolar capacitor on the capstan AC motor:

Time for a test! This is always an exciting step!
