General Information, Cable Information, Introduction and Performance Features
Introduction
Now you can take advantage of traditional McIntosh
standards of excellence in the MC1502 Tube Power
Amplifier. The 150 watt power output per channel
will drive any high quality Loudspeaker System. The
MC1502 reproduction is sonically transparent and ab-
solutely accurate. The McIntosh Sound is “The Sound
of the Music Itself.”
Performance Features
• Power Output
The MC1502 is a Tube Power Amplifier with a
capability of 150 watts per channel into 2, 4 or 8 ohm
Loudspeakers with less than 0.5% distortion.
• Unity Coupled Circuitry
The MC1502 Power Amplifier uses the famous
McIntosh Patented Unity Coupled Circuit which
provides low distortion, extended frequency response
and cool operating output tubes.
• Multifilar Wound Output Transformer
The MC1502 Output Transformer Windings are part
of the Unity Coupled Circuitry. There are two bifilar
wound primaries, one for the cathodes and one for
the plates. The secondary winding is wound together
with the primary windings. This provides very close
primary to secondary coupling. The result is flat
frequency response and wide power bandwidth.
• Balanced and Unbalanced Input
Balanced connections guard against induced noise and
allow long cable runs without compromising sound
quality.
• Sentry Monitor Tube Protection
McIntosh Sentry Monitor Tube Protection Circuits
ensure the MC1502 will have a long and trouble free
operating life.
• Vacuum Tube Sockets
Small Signal Vacuum Tubes Sockets have Ceramic
Base construction with gold plated contacts, providing
protection from atmospheric contamination. Output
Tube Sockets include Air-Pipe cooling at their bases
for long term operation.
• Amplifier Gold Plated Connectors
Gold Plated Input Jacks and Output Binding Posts
provide trouble free connections.
• Special Power Supply
A very large core Power Transformer and large
capacitors ensure stable noise free operation even
though the power line varies.
• LED Tube Illumination
Tri-Color LEDs illuminate the small signal processing
tubes of the MC1502. They indicate tube warm up,
normal and sentry monitor modes of operation.
