The classic award winning amplifier design of the original GFA-555mkII has been reborn.  Externally, the chassis footprint and 
front panel design are identical to the original.  Internally, all circuitry has been upgraded to meet ETL/ETLc, FCC, LVD and CE/
EMC requirements using UL approved FR-4 printed circuit boards.  High performance component selectons include ultra low ESR 
electrolytic capacitors.  The result of these improvements is lower distortion, better dynamic range, improved damping factor and 
greater stability and separation of individual instruments on the sound stage.
