Marantz 8


The model 8 stereo amplifier is essentially two 30 watt model 5 units in one compact chassis, and features the same high quality of performance.

All connections are made on the rear, making it ideally suited to exposed installation (for example bookshelves, room dividers etc).

With its optional grille snapped in place, it presents a smooth, uncluttered appearance with all tubes and wires hidden from view.

A simple built-in metered test provides assurance of correct operation.
