Couldn't load pickup availability
(see english version below)
This set consists of 50 electrolytic capacitors from the manufacturers VISHAY, FROLYT, TEAPO, JIANGHAI (JH), YAEGO, etc. (subject to availability).
In the case of the original 8,200µF/56V capacitors, better 10,000µF/63V capacitors are included here.
Most electrolytic capacitors are selected with higher voltage resistance and usually also have higher temperature resistance.
Both have a positive effect on the expected service life. Thanks to advances in electrolytic capacitor manufacturing, the fit is still guaranteed.
Complete recap kit for all electrolytic caps of the Marantz PM-250 and PM-400
Instead of the two 8.200µF/56V caps which originally are inside that amp, you get better 10.000µF/63V caps with this kit.
Why recapping?
Electrolytic aluminium capacitors are made from two aluminium foil strips and one paper strip. The paper is made wet with non conducting fluid
and coiled up between the two aluminium strips. That roll is housed in an aluminium housing and sealed with a rubber plate wich allows the two wire conductors to come out. It is possible that air gets into the two holes in case not good sealed due to oxidation of the wire, hardening of the rubber by aging or too high temperature or too long soldering process with melting the rubber where it contacts the wires. But extreme condition in the power supply like ripple current can make a cap hot and let the fluid damp away. Some caps have a ventilation hole wich opens in case pressure gets to high.
This is not an extreme example but I once had a PHILIPS 2200µF cap which measured as 1551µF after all those years. It can be more extreme and it goes on, the older your device gets.
Important notes:
You
should be aware of the dangers of working on open devices and only carry
out the work as a qualified person or have it carried out by a qualified
person, as there is a risk of electric shock as long as the mains plug
is plugged in.
Installing the electrolytic capacitors included in this
set requires knowledge of soldering on circuit boards.
If
you have doubts about your own soldering skills, please contact
someone who is familiar with it, e.g. a professional, and
do not use your classic device to learn soldering; it
may have a hard time surviving it.
Attention, electrolytic capacitors must be installed with correct polarity,
i.e. they have a positive (+) and negative (-) pole. On an electrolytic
capacitor with liquid electrolyte, the negative pole is always marked,
either by the side print or the shorter lead on new electrolytic
capacitors. It is advisable to take detailed photos of the previous
state and/or to mark all negative poles with a small dot (Edding) on
the circuit board before desoldering. The component print does not
always correspond to reality.
Our offer refers only to the spare parts kit, which is available in brand new quality.
We offer a 60-day right of withdrawal.

Installation and Assembly Instructions
This type-specific capacitor kit is intended to replace the
electrolytic capacitors in the respective device, either because the existing
capacitors are defective or because those we offer are superior to the
originally installed ones (upgrade).
1. First, it is advisable to take many photos: of the
wiring, the circuit board, and the capacitors. Since electrolytic capacitors
are mostly polarized (they have a positive and a negative lead or side), it is
helpful to be able to refer to these photos to ensure the correct orientation
when installing the new capacitor (in some cases, you cannot trust the circuit
board markings, if any).
2. Next, assess the situation. Keep in mind that in the vast
majority of cases, the new capacitors have a higher voltage rating 1.
3. Proceed step-by-step: desolder a defective capacitor 2, then solder in a new one.
1 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.
An example:
Your device contains four different types of 47µF capacitors:
47µF/10V, 47µF/25V,
47µF/35V and
47µF/50V.
We would supply you with the following replacement types:
2x 47µF/35V as a replacement for 10V and 25V
2x 47µF/63V as a replacement for 35V and 50V.
Although the original includes a 35V capacitor, a 63V
capacitor is supplied to increase the voltage rating.
2 In individual cases, we recommend desoldering with the help
of desoldering braid and a manual desoldering suction pump. The best option
would be an electronic desoldering station with a heated suction gun, but its
acquisition is usually not worthwhile for smaller projects.
