Kit with capacitors of correct brands and types for the CD disc drive servo board in several Bang & Olufsen models (but not all).
To see if this kit covers your servo board version, look at the solder side of the servo circuit board, in one corner you will find some numbers. Taking just the last five digits of the number, ignoring eventual punctuation marks (see photo), this kit will fit the following versions:
17001 (Found in some versions of Beocenter 9000)
17011 (Found in some versions of Beogram CD3300)
34186 (Found in some versions of Beogram CD5500, CD6500, CD7000)
35012 (Found in some versions of Beocenter 9000 and Beogram CD5500)
35013 & 35013A (Found in some versions of Beogram CD3300, CD3500, CD4500, Beocenter 9500 and Beogram CDX2)
The kit comes with a detailed component location chart.
And to answer a frequent question; Yes, of course this kit contains a correct replacement for capacitor C2103.
A small amount of high quality solder is needed for this job. Go here to find it.
