Hi, I was wondering what thermals I should expect from LM3886 on voltage like 40+40 DC?
Howabout when running 4 ohm speakers at full tilt?
What temperatures would you expect?

Hi,
If you have MS Excel, you can work with the design spreadsheet here:http://www.national.com/appinfo/audio/files/Overture_Design_Guide15.xls
The recommended power supply for 8 ohms is +/-35 volts. To go with higher rail voltage could trigger the SPIKE protection.

Thank you!!!
The last copy of that spreadsheet that I had didn't work.
Yours worked like a charm.
It also answered my NFB puzzle on how to get some serious headroom without going off spec.
