In the USA, electric power is delivered to homes in a "single-ended" fashion with two wires. One wire, called the neutral, is always held at 0 volts. There is no voltage on it. The other wire, called the hot, carries all of the 120 volts AC.

Not quite.

In the US, mains voltage supplied to the household is 220V 3-phase. Then its stepped down to 110V 1-phase to the typical household power outlet. However, large appliances are often run off the 220V line, wisely using different outlets and plugs.

Look at the specs for this table saw from Grizzly Industries and note that it can be wired for 110 or 220V.

For my future...  dedicated 100W AKSA bass amp  , I am planning the following:

Lower voltage supply rails (42V).
50% greater reservoir capacitance.
Higher current rated rectifier diodes.

This is to drive paralleled 8 ohm drivers with an impedance minimum of 2.5 ohms, so the increased current capacity within the output stage SOA might not be necessary with a single 8 ohm speaker.

Wow, Mike,

That sounds like some serious optimization  

I wonder what are the correct set-up, measurement and bias values with the lower rail voltages.

For my own personal application of driving a single 8" woofer @ 6 ohms impedence, I wonder if these measures are overkill....

I will read up more into it though.

Thanks for your valuable input!
