mc2102 vacuum tube power amplifier bandwidth in a tube amplifier thanks to an innovative mcintosh circuit high almost fifty years ago frank mcintosh and gordon gow invented and patented the mcintosh unity coupled output circuit two features differentiate from other designs first the output tubes deliver power from both their plates anodes and their cathodes not from their plates alone as in conventional circuits second the output transformer s two bifilar primary windings give it one-half the turns ratio of conventional transformers equating to one-fourth the impedance ratio this allows a close coupling of the primary and secondary windings resulting in wide bandwidth flat frequency response and low distortion the mc2102 is at once a tribute to the past and present mcintosh this characteristic is ideal for both analog and the latest ultra high-resolution digital formats the mc2102 will deliver 100 watts per channel into a full 20-20,000hz band and deliver that power with 8 4 or 2 ohm speakers balanced and unbalanced inputs and huge gold-plated speaker terminals provide the connectivity you need 2005 amplifier of the year the absolute sound g r e at 5 american classic men s journal magazine dual monoblock amplifier with all signal amplification by tubes tube compliment 8 kt88 4 12ax7a input tubes 4 12at7 driver tubes ceramic tube sockets with gold-plated contacts patented unity coupled circuit with bifilar-wound output transformers soft-start inrush protection remote power control trigger
