Hello friends, I have started a new project based on STK4231V chip for my long time interest. Personally, I have been a Stk fan boy since the time I got interested in audio line. Finally I get a chance to do it now. In the meantime, I know that recent Stk`s are not made from sanyo and also I know they will not sound up to the mark. But, I could not resist my thoughts on it. So, please don`t consider it a waste of time and money :D. As usual I look forward your appreciation and support.

1. Main driver PCB Made from JLC Pcb (gerber files courtesy 320volt.com)
2. Speaker protection with thermal resistance circuit pcb from PCBWay shred project.
3. Soft Start Pcb and Tone control as well as 15v regulated supply circuit as same.
4. Caps from Alcon Caps.
5. STK4231V from webspareparts.com (The vendor its manufactured form PMC) and the other one from Consolidated electronics USA
6. Parts from element14.
7. Ordered toroidal trfo 35-0-35v/5A and some parts. (waiting for arrival)
