McIntosh Laboratory's 50th Anniversary Amplifier
The latest model includes patented floating barrel speaker connectors. Now if one bumps one of the speaker wires, it doesn't loosen the tensioning screw because the wire will stay on the amplifier's speaker terminal. Ron showed me how the outer three small tubes can be used to determine which pair of KT-88 output tubes need to be replaced as one set, either right or left three tubes, will flash if there is a fault in the right or left pair of push-pull KT-88s. The center tube of the 7 small tubes is the single 12AX7 input tube.
For those of us who have the McIntosh MC275 on our bucket list, act now. Version 6 will only be made in a limited run of 275 pieces.
