Complete electrolytic capacitor set for all boards of the Bang and Olufsen Beogram CD 5500, CD6500 and CD7000
We now offer you the complete set, consisting of a total of 34 capacitors, which in the vast majority of cases have higher temperature and voltage ratings (see the description below this offer):
Panasonic-WIMA quality:
This set consists of 24 Panasonic FR-A capacitors, known for their audio quality and enormous service life, five WIMA MKS film capacitors for values below 4.7µF (as FR-A capacitors are not available for these values), also with excellent audio quality and an almost unlimited service life, and a long-lasting filter capacitor for the power supply.
Since the WIMA MKS film capacitor with a value of 3.3µF is no longer produced, we had to find an adequate replacement. We found it in the Panasonic EB-A electrolytic capacitor, which meets our expectations in terms of service life and suitability for audio devices (most capacitors suitable for audio have a highly unsatisfactory service life). However, this only applies to the one value, 3.3µF, for which four Replacement capacitors are supplied. The photo still shows the capacitors that are no longer available, until the photo is replaced by a new one.
We offer a 60-day right of withdrawal (for unused electrolytic capacitors)
General procedure for replacing capacitors
General procedure for replacing capacitors (see at the very bottom)
First of all, it is advisable to take lots of photos: of the wiring, the
circuit board, and the capacitors.
Electrolytic capacitors must be installed with the correct polarity; the
negative pole is usually marked by a strip on the side of the housing.
It is helpful if you can see which way the capacitor was installed—the one
you are holding between your fingers—so that you can install the new one the
right way around (in some cases, you cannot trust printed circuit boards, if they
exist).
In individual cases, we recommend desoldering with desoldering braid and a
desoldering pump. An electronic desoldering station with a heated suction gun would be best, but it is usually not worth purchasing for smaller
projects.
First, get an idea of the situation. Keep in mind that in the vast majority of
cases, electrolytic capacitors were supplied with a higher voltage rating.
The maximum permissible voltage (V) may be the same as that of the
old capacitor, but may very well be higher and must never be lower.
Voltage Capability
In 1987, Due to Europe-wide harmonization, the mains
voltage in some countries was increased from 220V (198V-242V was possible)
to 230V (207V-253V has been possible since then).
This may only concern Europe, but a similar situation is possible in countries with a 100-127V
mains voltage, with the same effect.
Due to the smoothening of the DC by electrolytic capacitors, which usually takes place immediately after the transformer and rectification, and with the DC voltage regulation only taking place afterwards, many such capacitors are now operated above the permissible voltage. The voltage capability was usually calculated very tightly due to the bigger size and higher price of caps with an increased one. This is particularly noticeable in Philips CD players, where the 16V caps in the power supply now run at 16V or above.
It is therefore strongly recommended that devices that can be switched from 220 to 240V (or from 100/110/120 one step increasing) be switched or soldered accordingly if you live in an area such a voltage increasement has taken place. Unfortunately, some do not offer this option; safety is then installed with an increased voltage resistance of the electrolytic capacitors.
Capacitors have become smaller over time, so that size is no longer an exclusion criterion for voltage capability.
An example of this:
There are four different types of 47µF capacitors installed in your device:
47µF/10V,
47µF/25V,
47µF/35V and
47µF/50V.
We would supply you with the following replacement types:
2x 47µF/35V as replacement for 10V and 25V
2x 47µF/63V as replacement for 35V and 50V
Although the original comes with a 35V capacitor, a 63V capacitor is supplied to increase the voltage resistance.
Temperature resistance
In the past, only capacitors were installed that had a temperature resistance of 85°C, as this corresponded to the state of electrolytic capacitor production at the time.
Today these can easily be replaced by ones with a temperature resistance of 105°C; Unfortunately, some capacitors on the world market are sometimes only available in 85°C versions.
A set may therefore also contain some capacitors that only have a temperature rating of 85°C, although we try to avoid this.
General procedure for replacing capacitors
First, it is advisable to take plenty of photos: of the wiring, the circuit board, and the capacitors.
Electrolytic capacitors must be installed with the correct polarity; in your case, the negative terminal is generally marked by a stripe along the side of the housing.
It is helpful to be able to check how the capacitor you are currently holding between your fingers was installed, so that you can install the new one the right way around (in some cases, you cannot trust the markings on the circuit board either, if present).
For individual cases, we recommend desoldering with the help of desoldering braid and a desoldering pump. Ideally, you would use an electronic desoldering station with a heated suction gun, but purchasing one is usually not worthwhile for smaller projects.
First, assess the situation. Keep in mind that in the vast majority of cases, electrolytic capacitors with a higher voltage rating were supplied.
The value of the maximum permissible voltage (V) may match that of the old capacitor, but it may very well be higher and must never be lower.
Voltage rating
In 1987, this was harmonized in Europe, which meant that for some countries the voltage increased from 220V (198V-242V were possible) to approximately 230V (207V-253V have been possible since then).
In other countries with 100-130V mains voltage
Because filtering by electrolytic capacitors usually takes place immediately after the transformer and rectification, with voltage regulation occurring only afterward, many such capacitors are already operated above their permissible voltage, which was often calculated very narrowly due to physical size constraints (particularly noticeable in Philips CD players).
It is therefore strongly recommended that devices which can be switched from 220 to 240V be appropriately switched or rewired. Unfortunately, some do not offer this option; in such cases, safety is achieved by using electrolytic capacitors with a higher voltage rating.
Capacitors have become smaller over time, so physical size is no longer an exclusion criterion for a higher voltage rating.
An example:
Your device contains four different types of 47µF capacitors, each installed in four locations:
47µF/10V,
47µF/25V,
47µF/35V and
47µF/50V.
The replacement types would be supplied by us as follows:
2x 47µF/35V as replacements for 10V and 25V
2x 47µF/63V as replacements for 35V and 50V
Although the original includes a 35V capacitor, a 63V capacitor is supplied instead to provide a higher voltage rating.
Temperature rating
In the past, only capacitors rated for 85°C were installed, as this corresponded to the state of electrolytic capacitor manufacturing at the time.
Today, these can simply be replaced with ones rated for 105°C; unfortunately, however, individual capacitors on the global market are occasionally available only in an 85°C version.
A set may therefore also contain some capacitors rated for only 85°C, even though we try to avoid this.
General note: It is becoming increasingly difficult to source the small electrolytic capacitor values 0.1µF, 0.22µF, 0.33µF and 0.47µF from current production.
If your desired electrolytic capacitor set contains these values, the very suitable for hi-fi applications KEMET R82 series film capacitors will be included instead from now on. For the same reason, once stocks are depleted, the WIMA MKS film capacitors with values of 2.2µF and 3.3µF will be replaced by the excellent PANASONIC electrolytic capacitors from the EB-A series.
