Description:
HTA: Hitachi Top Amplifier
B Class Mosfet Power Amplifier, using Hitachi's Mosfets 2SK1058-2SJ162.
Input differential stage and VAS stage are like Sony's ES 90's amplifer.
VAS is Cascode Configuration.
Output Stage use 4 devices, 2 N channel MOS and 2 P channel MOS, note the power voltage rail is NOT regulated, the signal voltage should be... anyway they must be separated.
100W Continuos Power into 8 ohm could be obtained with appropriate Power Supply
