*1 Recomended maximum voltage. Lower voltages can be used without problems, but with lower maximum output. A well stabilized +5V, 100mA supply is also required.
*2 VA rating is for general "domestic" use. For heavy duty use like PA and woofer amplifiers, increase the VA rating by a factor 1.5
*3 Some resistor values need changing
*4 Several components need oupgrading. Read in the forum for more details.
