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

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.

Finite output impedance sees to that, strictly. But on a practical
level, if your amp will produce double the power into 4 ohms, you've
over-designed it for 8 ohms.
