Default Icepower 200asc

Hi!
I've got a B&W sub that uses an icepower 200asc. For some reason, it has blwon 3 resistors. I'm looking for the schematics to see if I can repair it... can some one help me?
Thanks,

Bernardo Cabral

thanks for your link, but it's not the same model and I'm not finding something like the affected area on that one.

I'm uploading a photo from my board to see if anyone can provide me a photo from a working set!

thanks,

Bernardo Cabral

Hi Bernardo,

in my ASC200 they look like three paralleled 0.22 ohm 5% resistors.

Best regards,
George

Hi gagnou!

Thanks for your help! I'll try to replace them and then we'll give some feedback.

Thanks,

Hi
Interesting, I also have a B&W sub (ASW608) which has blown up. At the same area.. on my board it's not the resistor but the capacitor. It seems this a design weakness.. a lot of people have similar problems.
I wonder if it's feasable to replace the whole amplifier circuit with a module which can be purchased more easily than the Icepower one.
