Hello Everyone!
I think this is my 1st ever post here.... I just wanted to share my Apex H900TEF... Hope someone who built this Amplifier will be able to review this so others may be able to build using my layout. Once someone confirms that the schematic is correct I will share my gerber file or pcb layout....


Thank You
