Sundown SFB-8000D

Have one which came in with output FETs hardly working. One was almost shorted but not quite. I clipped a few off the board and the amp started to get a little better.

The output FETs are TO247 but are defaced. Anybody know what these are?

Im also going to replace the drivers ICs, as there are two in this amp; IRS20957S as I believe - scratched off as well; that is IF I can find them. Right now I can only seem to source them from eBay.

Does anyone replace the 6-pin ICs? zxgd3005e6ta as I believe. The problem with these is, they're not available anywhere from what I can tell.

This may be the last Brazilian/clone I work on if I cant find parts.

Thank you in advance.

Irs20957s is correct and good luck finding them at the moment. Do not buy ebay parts especially at this time.

-247 in the 12ks (Brazilian) IRFP90N20D I'd guess they would be the same in the 8k as they do not tend to shy away from using the same components across all their amps.

We are going to continue seeing a steady incline of especially SFB and Wolfram O-series, but Brazilian manufactured amplifiers as well. Former for quality (lack of) and the latter because the amateur customer base.
 
Can anyone vouch for them? Inventory has been more than a week since checked on most of them, the fact none of the big players don't have even 1 leaves me suspect. It's scattered when stock comes available and need to be quick as it does not last at all when/if it does become available.
