If this is what you mean,
yes this is bridge on both channel, this is what we used last Dinagyang,

Our latest power amp is a modefied K10, K10 using only 2 switching transistors, 7 for outputs we make it 4 for switching and 8 for outputs and change some components at the bias and driver section, we also change the buffer.

Ah ok but still look at your power supply not enough capacitors and transformer you use old e-core not good for a powerful amp better use a trodial transformer and many caps so you can load down to 4 ohms. good luck !

LOL thats already computed if you know how to compute the power needed in specific amp.
thats capacitors are enough coz the value is 22,000Uf not 10,000 Uf . do not question us about our design we know what we are doin.

any transformer will do if you know how to compute the desired power. for your amp.

Your transformer is too small, not enough to handle in two amps even your caps. How much total wattage in your amp of 8 ohms load stereo?

This is our first transformer and capacitors use in that amp, we try to change with a small one and monitor the supply voltage and yet not flactuating, so we decided to assemble that way.
