capacitor 4 -take 2

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....
