For all articles we assume a warranty of 12 months, calculated from the day of acceptance (except for wear parts such as potentiometers, switches, foils). The warranty covers the replacement or exchange of defective parts, whether as a result of design, manufacturing or material defects. The warranty is only fulfilled if no repairs have been carried out by unauthorized third parties and no spare parts of foreign origin have been used. The warranty is only valid towards our clients and only for the goods of one brand sold by us.
