The whole amplifier is designed as if it made of three separate elements.

1- Power supply: made with a 600VA transformer for each channel. The bridge rectifier is made with ultra-fast discrete diodes of 50 A each. 
The filtering capacity is 16800µF per branch so the amplifier has a total of 67200 µf filter.
At switch-on the current is limited by resistors variable with the temperature that after swoth-on are excluded from the signal path.
2- Amplifier: fully dual-mono also for ground connections and power supplies. The digital stages to control the volume chips are also optocoupled
3- Preamplifier: as for the amps, the preamp stages are dual-mono.
