Car amplifier Calibra stealth driver chip repair

[Leenesh]

Good day folks

This is my first post. I have a Calibra Stealth CAIH 2200
450 watt rms car amp that I am repairing for myself.

Was going to trash it and use it for a heat sink for my inverter project lol. But came across a nice amp repair chanel on YouTube that inspired me to test it. I think it was water damaged
In my car since my boot was leaking.

Tested all the fets and rectifiers seem ok. I am new to amplifier repair, but electronics is my hobby and I am a qualified Electrical technician.

I would like to know if anyone here could tell me the model of the driver chip since it was sanded off by the factory.

Thanks.

Never heard of it but most of my searches end up in South Africa --is it manufactured there ?

Thanks for the reply Duncan yes I'm from SA but amp says made in USA. Lol can't find much myself.

S494P - 509G bottom number its a PWM chip used in push pull amps etc.

Its been known for companies to rebrand their makes or models when exported to a foreign company , according to the USA government trade policies countries external to the USA are classed as "foreign " countries and that includes the UK.


Its possibly sold under a different name in the USA or its an "export only " design , the UK did the same many old tube radios were "export only " with stations marked in the country it was sent to.


I will try Tor in case I am being restricted in my searches but I keep getting --ZA .

Right there is a Calbra INC in Delaware USA but I tried a USA business lookup and it got me an Apple subsidiary but I have my doubts about both .

The S494P is not in production any more but there
Is a replacement the TL494.

I'm also keen on Valve tube amps built a 100watt Marshall tone stack push pull using electrico harmonix el34 x 4 tubes
And 12AX7 preamp tubes. Man it felt amazing when I got it to work. I felt I can build anything after that lol.

Now I'm hooked on electonics

Post a good quality photo of the component side of the entire main board and the component side of any driver boards if no one can help.
