2008多項課程召集 - (8) DIY入門理論班 (FULL!) / DIY入門實踐班 (已完結)

I want to join the course. Would you mind telling me more detail about the course.

I have made a USB DAC before. Is this course suitable for me?

If it is not suitable, can you recommend some course for me. I want to make a Power Amp, DAC or CD player.

Thanks

Is 初級音響電子入門工作坊 included DIY入門實踐班 and DIY入門實踐班 ?
if not, what is the different between DIY入門實踐班 and DIY入門實踐班 ?
How much for each course and how i can apply it?
thx
