An Arjen Helder tripath board with smps in a custom made aluminium chassis, anodised in black.

Improvements to the PCB:
- 400 volts 2.2uF audio grade film capacitors with excellent dissipation factor ( 0.006 % @ 10KHZ )
- Bigger board size for more space to replace components
- Thicker PCB material, PCB is now 3mm Thick!!
- Bigger output coils, with Micrometers T68-1 Torrodial core for a much improved transient response
- DC offset adjustment with high grade 10 turns photometers
- Signal lights for power and overload are separately connected with connectors
- Extra large 6800uF 25 V buffer capacitor ( more than 3 times bigger than the competition )
- AC and DC power input supported ( rectifier onboard )
- Very wide operating voltage 9-15 volts, perfect for people that run off of batteries
- Copper mounting studs for easy mounting in the housing
