Re: Infinity PS-12 Powered Subwoofer Fired Amplifier

My Infinity Entra Two is working good as new.

Not sure if this is visible to others but here is the bill of materials I used at Digikey for the caps.

My board was a first revision so I used the original caps except for C37 which I upped to a 270uF since my sub normally didn't stay (green) on for the full 10 minutes before going back to standby after no input (now it does)

Add to this the small ceramic...

I know this post was from quite a while ago but I'm wondering how this worked out for you? Looking at that last picture it seems C71 exploded (and it took out D34 with it)!!

Here's a picture of mine and you can see the same exact part failure (this is on the bottom of the board just in parallel with the crossover cap C73 that was bulging) BUT mine was not nearly as bad.

So I have replaced all the electrolytic caps and the two crossover bipolar caps and have just ordered a replacement...
