capacitor 4 -take 2

semi product---- i have changed 2 solen capacitor and 1 solen coil & resisitor. improve the sound performance by 50% I feel the sound is much more solid but not enough 通透



i will change the 5w 2.7Ohum and copper cone which the position in the right handside.
And then i want to ask what is the function of coil ( both the left and right handside) ?

how much u buy the 10uF &5.6uF solen cap in HK?

if not mistaken u can by pass (put parellel) a 0.1uF wima black box or UCC SPP to improve high note/high frequency. (Solen cap high side a bit less)

the coil is inductor, if u can find good quality/purrer cooper with same inductant (mH), sound can be improved....
