  • Carver A-500x/A-760x/A-753x

       (1 review)

    The A Series Carver Amplifiers were late in Carver's Production years. Although not Magnetic Field Coil amplifiers, they still inherited many of Bob's amplifier topologies that create an accurate, musical and powerful sound reproduction. Although the extent to which Bob was involved in the A series design is not know, it is unmistakably an extension of his earlier designs.

    The A-series amps utilize voltage rail switching to produce immense dynamic power without having to add cumbersome heat sinks. The high voltage rails are engaged by Power MOSFETS which modulate to the output signal and turn on only when the music amplitude demands, feeding the output sections that are direct coupled with multiple paralleled transistors for high current output.

    Featuring bridge-tied mode, gain adjustments for each channel, VU meters and 5 way binding posts, the A series power amplifiers are remarkably suitable for almost any musical set up.

    Our restoration addresses minor failure points, replaces all consumable parts*, calibrates the signal transfer function, and a full cleaning inside and out. We also offer an IEC socket modification, Gold RCA posts, Gold 5-way speaker binding posts, and meter light LEDs for an additional fee.
