OK How abot this one:

100 watss into 8 or 4 ohms depending on power supply voltages.

Why not use a parallel configuration of two LM3886 or one LM4780 amp? No phase inversion needed and it can easily drive less then 8R speakers.
LM4780 stereo/parallel

I am driving 6 Ohms speakers with LM3886 bridged and they don't get very hot
My trafo is 20-0-20 .....
BTW, the LM3886 plays very well when it's hot
using +/-30V results 160Winto8Ohm load(using theOverture_Design_Guide13)veteran said:Theoretically You should get 'real' 100W on 6R using this configuration of chip-amp. But if You wont more power - look for some discreet bipolar or mosfet amplifier.
so i was hoping at least 120W
Bridged amp will drive a load of 4 ohms , but the protection will not allow to reach the highest power levels.
To get 160 w RMS you will have to keep ur chip temperatores low.That means a large heatsink , and a fan. I think it is better to use 4 chips instead , and have 200 w RMS without a fan.
Did you read BPA - 200 app note ?
