Mcintosh MC-2505 Power Amplifier (1967)
The McIntosh MC2505 is a solid state power amplifier with a maximum power output 50 watts per channel operating simultaneously, into 4 ohm, 8 ohm, or 16 ohm loads.
"When introduced in 1967 the McIntosh MC-2505 was a revolutionary amp in many respects and served as the blueprint for all future McIntosh amps to come. Not only was it McIntosh’s first solid state amp ever, it was also their first to have a full glass panel faceplate, precision calibrated output level meters, the panloc mounting system, and it was the 1st sold state amp to incorporate McIntosh’s famed Unity Coupled Autoformer for full rated output at 4,8, or 16 Ohm impedance."
