Description
Enhanced Hiraga 8w A class amplifier Do It Yourself Kit which can deliver up to 15W. This kit have everything what you need to make your own A class amplifier.
The original Hiraga Amp transistor are replaced with 2SC1775+2SA872 and on output NJW0302G+NJW0281G .
The output transistors must be mounted on heatsink and heatsinks are only components which are not included in this kit.
Driver transistors are 2SB716 and 2SD756 jfets are 2sj74 and 2sk170 .
Decoupling capacitors are from Elna (Cerafine or Silmic II series), so everything is designed to satisfy very rigorous standards.
Transformer: For max. output it need (2x 15-0V) 100-150VA per channel
pcb is FR4 1.6mm 2oz Red (immersion silver which need to provide the best connectivity and audio quality.Immersion silver pcb’s are also most expensive)
