Default Bridging of the Gainclone ??

Is it possible to bridge two GC circuits - I'm thinking of bridging two LM3875 devices - is it possible, and how can it be done ?
Should it be driven by a balanced source ?
What would the power be - 150watts ?

Cheers !

Hans

Take a look at the National Overture app notes - it describes bridging and paralleling up to 200w.

I believe they were referring to this application note:

http://www.national.com/appinfo/audi...ation_Note.pdf


or


Look at part 7.0 (pretty much the same as above) at this link:

http://www.national.com/an/AN/AN-1192.pdf



Hope these help.
