Class A Stereo Power Amplifier
The MA-260 is a 2 channel stereo power amplifier in pure Class A operation. With the use of 5 pairs carefully selected and matched powerful MOSFET transistors per channel (10 pairs in total), the MA-260 is capable of delivering a guaranteed linear output of 45 watts x 2 into 8 ohms.

Each of the MA-260 power amplifier is handcrafted with the use of highest quality parts and components. The audio grade toroidal transformer is custom wound according to our specifications. Even the heavy-duty special designed heat sinks are custom made in order to meet our standards.
MA-260 Highlights
