Hello Guys,
This is my first post, so any help would be dearly appreciated.
I opened up my faulty b&w pv1 subwoofer.
The power supply and amp board are covered in low quality SMG capacitors, rated at 2,000 hours 85 degrees.
Im totally lost - it took 2 hours just to open the subs (due it being and glued together) The amp board is a b&o ice power 500A (won't be recapping that)
so while I have this thing open I plan to replace all of the caps. Can someone please recommend the best caps to use. ie which Nichicon, Panasonic cap series to use.
Thank you for your kind assistance

Any Panasonic EEUTA1 125℃ or EEUFC1 105℃ capacitors will give good service, don't waste your money on faddy makes.

Before you spend a cent and risk introducing new symptoms.
Maybe you should tell us what the fault is.
The caps (that visually look fine to me) may have nothing to do with your problem.

What you mean with low quality?
Those caps are United Chemi-con (SMG is the line series) they are as good as nichicon or panasonic they are specialists in that stuff.
What make you think those are bad?

"Before you spend a cent and risk introducing new symptoms." Very good point especially as those PCB's look like 2 layer or more and as a result unsoldering any component will be tricky, very easy to damage traces and via's. Think on before blanket recapping, find the fault first.

The caps are fine - I thought that it might be a good idea to replace them while I have the unit open. But after considering your advice, I may just leave them alone.
The unit powers on, but there is no sound when a signal is fed through.
Im aware that they are United chemical, just thought they were bad due to the following reasons:
1. rated at 2,000 hours 85degrees
2. there have been numerous threads about these caps failing in the b&w Pv1
So I thought it would be better to replace them with a Higher temp, longer life cap.
