Yeah, sure!

I'll post up as much as I legally can, cos the circuit is part of a company's new amplifier project that I am currently modifying and testing.

I'll scan it, and post it asap.

I essentially incorporated a speaker relay cutoff circuit from this source:

However, I took out D1 and C1, and connected it directly to the 12V bridge rectifier I had in the circuit already.

Oh yeah, and to answer the power amp question...

I'm using 2 x LM3886 running in parallel with each other.

The LM3886 produces 68W into 4ohms, and 38W into 8ohms.

But like I said, I'll try and post as much of the circuit diagram up as possible asap.
