I purchased the subwoofer 'Rocket ULW-10' around 2005 and recently was experiencing a humming noise coming from the sub. So I researched the problem on the internet and it was suggested on various forums that this could be a capacitor issue.
After checking the audio source and for grounding issues, I then decided to open up the subwoofer plate amplifier. What I discovered was that 2 of the capacitors on the power supply board were blown.
The 2 capacitors had the following specifications:
'PEC' or 'REC' , SR , 1000uF , 25V , 85C
Now I am assuming from looking at the power supply that it is a linear design and not switch mode design.
What would be a good replacement for these capacitors ?
