In the amplifier , it can work in well without compensate capacitance , the capacitance's capability can change the tone color ,so it can choice 0-33P .

Thanks! But I mean something different. I mean voltage VALUES :-)

 27th December 2004, 01:58 PM #35 diyAudio Member   Join Date: Oct 2004 The voltage is +-30V to +-60V , it can work well, if change some parts , it can use higher voltage

What is each output stage transistor quiescent current value?

 27th December 2004, 02:28 PM #37 diyAudio Member   Join Date: Oct 2004 About the quiescent current value ,It's different value will have different sound. In my model amplifier ,the each output stage transistor quiescent current value is 75MA, total is 300MA. I've this PCB, only need \$8.75 (2pcs, stereo board , without postage.)
