Information
                                    The Adcom GFA-555D is a stereo power Amplifier rated at less
than 0.04% THD from 20Hz to 20kHz with 200 watts into 8 ohms
and 325 watts into 4 ohms. The output stage Is capable of
greater than 60 amps into low impedance loads. The Amplifier
employs a discrete differential Class-A front* end followed
by a Class-A voltage gain stage which amplify the input
signal to the voltage required at the output of the
amplifier. This high-voltage signal drives the high-current
triple-Darlington-follower output stage which amplifies the
current by a factor of about 50,000.
