I built one based on the Ambit PCB but then built the JLH regulated
supply which has relay protection for the L/S. One channel on that
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?



I'm sure that's something Stuart Pinkerton claimed of his Krell (not
sure of any of that spelling) amps on this NG, many years back. He used
to trot it out quite regularly and I don't remember anyone challenging
it . . .
