INTRODUCTION
The Hafler SE-240 is a two channel audio amplifier which
has been engineered to meet high performance and
reliability standards while maintaining affordability.
The amplifier employs a sonically proven circuit topology
driving MOSFET output devices. These devices provide
exceptional reliability as a result of their inherent rugged-
ness and resistance to abusive operating conditions. Con-
sequently, the SE-240 is capable of delivering high current
into low impedance loads, and generally the amplifier will
not be damaged in the case of an accidental short circuit
at the output. The drive circuitry is a high performance
arrangement with a double differential JFET input. Quality
components are used in the design to ensure longevity
and, above all, sonic excellence
Functions fine, some scratches.
UPS preferred. PP add 2.5% please. Double boxing.
