A little circuit that generates +18V from the power transformer in a NAD C375bee Amplifier. Why the complicated circuit just to generate the +18 volts? What is it doing different than an simple rectifier/filter? Does it have a faster/slower rise time? Faster/slower decay? Sure doesn't seem to regulate at +18 too well, but the designer must have done this for some reason. Attached schematic snippet from the NAD manual and my .asc.
