Generally, apart from the Beomaster 900K and 1000 which doesn't
really suffer from major cap problems - at least not yet,
capacitor kits are available for most Beomasters, Beocenters,
selected Beograms, Beocords and most Beovox speakers of
the 1970's and 1980's plus a few others.
Prices vary according to the number and types of components in the kits. Some kits contain only a few, but essential, components, others as many as 70 or more.
Due to their nature, the caps are of different sizes though most of the radial (cylindrical) caps are board mounted 5mm pitch. Basic soldering tools and skills will do fine.
A few cap kits actually contain more than caps in that other components prone to failure can be included.
