I didn't notice that.   I never use anything greater than CD quality (16/44k1) and the experts (http://www.hydrogenaudio.org/forums/) say you can't hear any difference from higher sample speeds or bit depths. In fact there are...

Thanks are due to KT88, who pointed out that the bases of the transistors can be driven too negative (or positive in the case of the PNP) in this arrangement. This is easily solved by the addition of a couple of diodes.   He...

The coax is regular SPDIF, not optical.   The transformer has 15-0-15 and 9-0-9.. It's good for a total of 30watts.   The amplifier wants 240mA 15-0-15, that's ~7.5 watts. The transformer probably splits the power...

Thanks, KT88, but what took you so long? We could have been here about 60 posts back...       w

But not now. Thanks...               w        

And I'm saying you're categorically wrong when you say that -6V will destroy a 2N3904       w

What are you saying, the regulator circuit doesn't have output transistors?   w

I'm happy to leave it to readers to judge.   wakibaki versus goldpoint, same capacitance, ideal voltage source in goldpoint...         w
