Hello, I lost that schematics, too. please Albert, can you help us.

cheers

I'm out of the UK until Wednesday so don't have access to my big HDDs. I'll put it up then.

I've also got a couple of other design options of varying complexity. The more complex they are, the closer to "industry standard" they get. The more complex ones also have lower noise and distortion, but in most cases, you're not going to be able to hear any difference.
