SOURCE: k3569 transistor not found, so

Follow this link in order to get to the substitute for your transistor (2SK3569) from On Semiconductors. Check that your ...K3569 is also a Power MOSFET N-Channel transistor.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Thanks and regards

The type of audio power and the number on onkyo A917 amplifier


Hi
Usually there are 2 transistors for each channel, if you don't know the numbers on the transistors.
there is another way to get as close as possible to have equal or similar to the same type of transistors (NPN/PNP)
example: 2SA is PNP transistor.
there are (2SA/2SC) transistors and there are (2SB/2SD)
complementary transistors
1: you have to know the supply voltage for the transistors
2: choose transistors that it is equal to the current and voltage that suits the supply voltage.
follow this link to find suitable transistors.
be aware and be careful that there other parts you need to check on the power amplifier circuit, resistors,capacitors and drivers etc...
I would suggest (2SD1047/2SB817)

Good luck

Sony xplod 1200 watt amp quit no kind of protect lite on please


short answer yes... Long answer... Amp Failure: There are many different ways that an amp can fail but the two most common failures are shorted output transistors and blown power supply transistors (< those are not blown). There are several types of protection circuits in amplifiers. The most common are over-current and thermal. The over-current protection is supposed to protect the output transistors. Sometimes it doesn't work well enough to prevent the failure of the output transistors but it will work well enough to shut the supply down before the power supply FETs are destroyed. If the amp remains in protect mode, goes into protect mode or blows the fuse as soon as the remote voltage is applied, shorted output transistors are almost certainly the cause. If the fuse protecting the amp is too large, if the protection circuit doesn't respond quickly enough or if the power supply is poorly designed, the power supply transistors may fail. If you see a lot of black soot on the power supply transistors (near the power transformer), the power supply transistors have failed. Soot on the board doesn't necessarily mean the transistors have failed. Sometimes, technicians don't clean up the mess from a previous failure. Transistor Failure/Checking Transistors: In general, when a transistor fails, it will either short (common for output AND power supply transistors) or open (common for power supply transistors). Transistors act like valves. They control the current flowing through a circuit. A shorted transistor acts like a valve that's stuck open (passing too much current). In the case of an output transistor, the shorted transistors tries to deliver the full rail voltage to the speaker output terminal. If you've ever seen a damaged amp that pushed or pulled the speaker cone to its limits when the amp powered up (common on some Rockford amplifiers), that was almost certainly due to a shorted output transistor. When checking transistors, you most commonly look for shorted connections inside the transistor. You do this by using a multimeter to look for low resistance connections between the transistor's terminals. Note: I used the terms short and open on the previous paragraph. A short (short circuit) is a path through which current flows that should not be there. An open (open circuit) is a break in the circuit. It is most likely the power supply that has taken a ****.

These repairs are best left to a repair tech familiar with car audio amplifiers. Check with your local shop to get a reccomendation. If the light isnt even coming on, chances are your input or power supply has been taken out.

Seems as you have blown an output. Seek repairs.

Transistor


The first letter: A = Ge material semiconductors, B = Si material semiconductors, C = GaAs material semiconductors, R = Compound material. The second letter: A = Diode (low power, signal); B = Diode (variable capacitance)); C = Transistor (low power, audio frequency); D = Transistor (power, audio frequency); F = Transistor (low power, high frequency); L = Transistor (power, high frequency); R= control and swithching device); S = Transistor (low power, swithching); T = thyristors; U = Transistor (power, switching); X = Diode (varactor, multiplier); Y = Diode (rectifier); Z = Diode (zener). So the BC547 is a Silicon low power, audio frequency transistor. Hope that helps!
