Replacing Bel Canto S300 blown ASC200 module

So I have lost left channel on my S300 and after reading up on the amp a little and realizing that Bel Canto seems to have just wrapped two ASC200 modules in a nice case, maybe I should just order a new module for $129 and replace it myself.
A couple questions for smarter people than I. First, the ASC200 (at parts-express) says it is rated at 200W @4ohms, but the S300 says it is rated at 300WPC @4ohms. How can this be different? Second, looking at the pictures of the inside of the amp, this looks like an easy plug and play--is it so simple?
I know nothing about the Bel Canto, or Icepower ASC200, so take this advice for what it is. I had the Ice Edge 1200AS2 modules.
Looking at the spec sheet, the ASC200 using 230vac/50Hz @10% THD+N is rated at 290W - so it's close to the suggested 300W.
I would try removing the bad ASC200 module from the case first. If you see no issues doing this, then 'yes' it can be so simple. If you feel there are issues removing it beyond your capabilities, then it isn't so simple.
I would also consider ordering 2 modules at the same time and installing both new modules instead of just replacing the broken module. Use the good/old one as a backup. If you decide to order 2 modules at the same time, remove both modules first to make sure you don't encounter any unknown issues before ordering the modules. Typically, these modules for this type of installation really are very simple plug and play.
Yes stock older icepower in that TTBOMK.  Make sure you get the right Icepower board.

If you can’t do it yourself worth a call to Bel Canto to at least determine if repair cost worth it. They did work on one of my ref1000m Class D amps several years back for reasonable cost and turnaround in just a few weeks. Replaced the proprietary input stage in that. Came back good as new.
Thanks Golfnutz--you know how it is, when something looks so simple you think you must be missing something.
It is the same 200ASC module.  I still have Rowland model 102 based on the same module.  300W specification, as golfnutz stated, is based on 10% distortion.  Rowland rated it only for 200W.  As I remember I took very long time (few hundred hours) for the sound to get smoothness and improve extensions - be patient.

Thanks Kijanki--I bought this amp used so it was already properly broken in. I am thinking it would be best to do as golfnutz says and buy two modules and just refresh the entire thing.  Then I can burn in both sides as you say--few HUNDRED hours??  Wow!
Just one more thing to mention ukthunderace, make sure you take pictures while you're doing this. You probably won't need to use them, but better safe than sorry.
great idea--make sure all the wires go back in the right places and I don't blow myself up!
You might blow the amp up, but I don't know about you going with it. Good luck... it seems like a great way to fix these.
Well that took about 5 minutes...I honestly didn’t believe it could be so simple.  Makes me want to spend some time on the diy forums and see what else I might be able to do.  All in, it cost me $136 to put a new left channel in the amp....I have a feeling Bel Canto would have charged me a bit more than that.
@ukthunderace  Congratulations.  Not only satisfaction of fixing it yourself but also assurance of being able to do this again (god forbid) in the future.
