Interesting!
Do tell us some more.

This circuit diagram Yorkville use in 50w guitar and keyboard amp, active stidio monitor, active PA speakers, small powered mixer... Circuit is simple R5, C5 and D1 make turn on/off delay on mute pin. I made over 80 PCBs, and use PC procesor heatsink for cooling. Most of them work in 2-6 channel amplifier for caffe-bars. Work great over 2 years in all condition even sumer heat. I you are beginer in DIY, start with this amp.

Nice PSU PCB, 10000uF can be used for stereo.

nice.
A lot of thought gone into the routing.

Hi Audisoul,
could you seperate the component overlay and the pcb traces and post them and give some more parts and connection info. My monitor is not brilliant.
Thanks
(also give the pcb size in mm's)
