STEREOPHILE.COM: MCINTOSH LABORATORY'S 50TH ANNIVERSARY AMPLIFER
|It was good to visit McIntosh
Laboratory's 35th floor suite at the Venetian Hotel and spend a few
minutes with Ron Cornelius, the product manager, discussing our shared
experiences with the legendary McIntosh MR78 FM tuner. Ron showed me
the latest iteration of the company's MC275 tube amplifier. Now
released as version 6, 50th-Anniversary 275, priced at $6500, it reminded me that the amplifier was first shipped in 1961.
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.
