แบบแก้กราวน์หน่อยนึง
C in put ขยับด้านข้างนิดนึงใช้หางหนูตัวยาวๆได้เลย
C in put กับ R out put นี่ค่าเท่าไหร่ดีครับ
แต่ถ้าไม่ใช้ ใช้ลวดจั๊มเล่นเสียงลวดได้เลย
And is anyone able to tell me how often the copperwire has to be wound around the resistor for R/L? ANd does it have to have a diameter of 1mm? or would 0.8mm would work too?
I used 0.8mm, 10 turns tightly on the body of 10ohm/3W resistor.
Here's how I did the layout. Although the traces are only 86 mils in width, they are covered with around 0.5mm solder layer and thy withstanded an unwanted shortcircuit between the negative rail and ground. The chip leges melted, the tracks were fine.
