MARANTZ DESIGN AND SERVICE

Using superior design and selected high grade components, MARANTZ Company has created the ultimate in stereo sound.
Only original MARANTZ parts can insure that your MARANTZ product will continue to perform to the specifications for
which it is famous.

Parts for your MARANTZ stereo are generally available within 72 hours throughout the nation via a toll-free line to our
National Parts Depot in California. The sales professionals who take your call immediately refer to their own desk top com-
puter terminal and can quickly determine the availability and price information you require. If for some reason, your order
should exceed our available stock, we usually can instantly provide an alternate replacement part or current delivery infor-
mation. When the order is placed and confirmed, the computer simultaneously generates "hard copy" orders at the
distribution center. As hard copies come directly from the computer to the national parts depot, your requested stock is
assembled and prepared for shipment and placed on the first available carrier for delivery to you.
