Have a few problem in circuit.

1. I drew the wrong and that you was copy the wrong to your circuit (see picture)

2. MPSA42/92 not be used with +/-75V in the Vas .

3. Current of Vas the same as your circuit is (2.4/257.5)/2 = 4.66mA not 6mA you wrote in circuit.

I practiced many times, to have the same value! Schematic you gave false and not true reality! The values ​​given are based on my practice many times, finishing last, but maybe it is just the beginning of the capacity. __________________ ES9038PRO: http://www.diyaudio.com/forums/group...ml#post4907889 http://www.audiodesignguide.com/DACES9038PRO/index.html Last edited by quanghao; 19th December 2011 at 08:55 AM.

Right the same as normal, but wrong the same as is sure to copy. In here,many people have good knowledge,they will see now. __________________ Ultraline1@gmail.com Last edited by hien.t.nguyen; 19th December 2011 at 09:19 AM.

You have no knowledge of electronics so your practice does not mean.

If you have knowledge of electronics,you did not draw like that(you say your circuit is right).

Please see the image, line I is fixed. I = I1 + I2, I1 I2 increases, the reduction should decrease the VCE.
VCE Q29 is inversely proportional to I2 so P = I2.75 = 4.66x75 = 349mW <625mW.

What do you think it??
