Guys, why are some manufacturers still masking part numbers even on designs that aren’t proprietary and the part itself are been re-engraved by them?
Is it that they are making the repair harder, or they only needs the item to be repaired by their authorized centers?
Have anyone seen the newer SoundStreams (Taramps look alike circuit)....
What could these part numbers be?;
The output marking H8 and what IC are they driven by?
Power supply FETs H1 and what PWM chip is driving them?
What is the error amp IC number?

I noticed this on another amplifier as well. I have to look back and figure out which brand it was.
I am wondering if this is the new korean design and they are just trying to protect their IP.

This looks to be made by Soundigital.
They are notorious for masking their parts
i know they make some Ground zero and some Alphard amps as well.
Whats wrong with the amp you have ?

No idea why Chinese copies are however they are not exatly the same part numbers between "Brazilian and them. Sam does have a few videos on these giving part numbers as well.
I spoke with Sam about this site, I will have to again next time I talk to him. One very informative video is "So you want to repair SOUNDIGITAL amplifiers? Tips & component values"
-220 Package output fets tend to be 4127 or 4321. Soundigital C1=IRFB4127 and C2=IRFB4321

Yea we exchanged a few messages, sent some pictures also, he gave me a few possibilities....but wasn’t definitely in the possession to confirm the real part numbers behind the design.
I have an amp with the exact same problem, have you found the H8 part number yet?
