ZEN like frontend drives Push-Pull Class AB - 16 Watt

[lineup]

Mr Pass ZEN is something I always return to.

This amplifier uses a ZEN input + VAS.
Drives the output in Push-Pull Class AB.
Output is biased 275mA.
Max Power out is a bit more than 16 Watt at THD 0.100%
At 1 Watt the distortion is 0.013%
The voltage Gain is like x12.

There is no need for compensation caps.
Bandwidth is 3Hz - 200kHz.
That is enough to make a good audio amplifier.

I thank Nelson Pass for liking this my design.

Now improved.
Higher bandwidth: 350kHz
Lower distortion: THD 0.008%
Better bias: 230mA

This is the designed amplifier I am most pleased with.
Even Nelson himself likes it.
You should build it. It is simple but good.
It delivers 16 Watt with rather low distortion.
