A Stereo Power Amplifier available ready built or as a kit. Intended for 120 V AC 60Hz in the USA, for use in other countries a multi-voltage power transformer is available at extra cost for 100, 110, 120, 200, 220 and 240 volts 50 or 60 cycle AC mains.
The Hafler DH-222 Bridging Kit is available to enable conversion of the DH-220 into a high power monophonic amplifier, bridging the two conventional channels into a single floating output which can deliver in excess of 400 watts into an 8 ohm load. Its rated power output is 350 watts across the audio band.
Semiconductor Complement :
26 transistors. 8 power Mosfets, 29 diodes, 4 zener diodes. 1 diode bridge.Power Rating:
