Nice tiny design. But would you mind uploading the PDF files of the PCB layout and schematics with more information on operation and construction and tuning the quiesent current preset ?
Thanks a lot
Please read instructions on PCB - Alll Layers.pdf - Biasing adjustments detailed here. Sorry , I not good at writing guides. But I will post a detailed guide with pictures as soon as I'm done.

Thanks for the PDF files. As you have mentioned about your 2 channel design, see that the two sections which can drive 100 watts each can be bridged together to be used as single 200 watts amplifier which may be ver usefull when used with sub woofer setups. Good luck.
Hi Pranam77. The 2 channel design can be bridged. It uses 2 x TIP142 & 2 x TIP147 transistors together with TDA7250 driver IC. The design is a bit more complex but will surely be ideal for subwoofers!
Just having a hard time designing the pcb as there are quite a few components which I'm trying to route single sided.
