When doing Class A we may be restricted to not as high Wattage.
After all we will not use many of those Watt.
With normal speakers the sound can be loud enough at 1 Watt output.
I have designed to have 16 Watt output.
For this I select to bias 1.20 Ampere through output.
My amplifier does not use many transistors.
Only those who can give a very good result.
As you can see from the simplified diagram
I use single power supply, so one transformer feeds two channels.
One 30 VAC winding per channel gives 40 VDC for each.
This of course means I use output capacitor at half the supply.
