Default MOSFET amp - thump at switch on.

I built one based on the Ambit PCB but then built the JLH regulated

decided to sit at about 120mV and there was no way I could get it
down. The supply rails were almost identical so I can only assume that
something has slipped in the amp design.

Without a doubt though the best power amp I have ever heard. Does 112W
into 8R and 224W into 4R - and that takes some doing!



**It's also impossible. No amplifier can exactly double it's power into
lower impedance loads. Your measurements were wrong.



Not even an ME1500?
Or any amp with a regulated PSU.
