Updates of PDF manuals

In these days I updated PDF manuals. The benefit of the PDF documents is the vector based schematic and PCB design for unlimited magnification, and the project is not separated to articles, there are all in one documents. Here are the updated documents:

• TDA7293 modular project: modified the wrong parallel schematic and PCB module, and inserted offer to make amplifier up to 800W with more than one parallel modules. Two new PWM fan controller and speaker protection design included.
• Headphone amplifier with TPA6120: Two schematic for the simplest and full featured solutions, but four PCB designs available.
  

My next "project" is to finish PDF manual for my parametric EQ.
