thanks for putting this up. Very interesting. I have no knowledge of PCB repair but tore down my B210A to fix intermittent cut out of low frequency speaker. The fix is beyond me but it is very interesting to see what you did. Thank you.

For comparison an old power amplifier repair:

That was a lot of work, and while I might question some of your techniques, you have a well working amplifier for the price of a couple of FETs and a lot of elbow grease. Very nice.

Got another one same type speaker with the same problem.
It seems to be that this is kind of type problem – those small capacitors age as they are placed just next to the hot regulator chips…

If you can’t find 1 uF 50V bipolar electrolytic it seems that 2.2 uF 50V will work OK in that place…
