III: OPERATION
3.1 COOLING
3.11 The Model 1100 uses side-mounted, convection-cooled heat sinks for power transistor cooling. When rack
mounted, temperature rise should not be excessive for eight-ohm loads at normal listening levels, but operation
into lower impedances at high powers may cause heat build-up unless good access to cool air is provided at the
sides of the rack. If side clearance and/or louvers cannot be provided, some space should be provided over and
under the amplifier for air circulation.
