I used the Laterals on my original board design found here.

I've been listening to them with Laterals for over two years and perfer the sound.
But I see what you may be getting at. It could sound different with the new design. I let what have working break in some than I'll try the Laterals. It's an easy change.

Clipping
Hi All,
The THD figures are very good, this amplifier is "promising".
Can you tell us something about the clipping charateristics of this amplifier.
Maybe show us some clipping pictures........
thanks,

I like the pcb layout, looks very nice to my eyes - overall construction is very tidy and professional looking.
hi Al(l),
Is the output capable of swinging from rail to rail?
If not, how much is lost?
Maybe it is an option to provide the CFP with some (small) gain to compensate for the voltage loss.
Nice PCB board !

Hi Piersma,
It cannot swing rail to rail. With a 0.7Vrms input and +/-50V rails the maximum output into 8 ohms is 100 watts (28.3Vrms, 40V peak), 140 watts into 4 ohms.

Hi Piersma,
I simulated your circuit, it doesn't work well. Unfortunately I don't have the time at the moment to analyze the amp circuit design to see whether there's a simple way to achieve rail-tail-rail without degrading performance. If you come up with something else I'd be happy to take a look at it and run through the simulator.
MikeB's and Roender's circuit design that I've implemented on my new PCB has far exceeded my expectations. I think it would best to leave the way it is.
