You need to post the reference number of the IC into Google. My reference book shows that Technics is connected to Panasonic, but it could be out of date.

SOURCE: TA-1080 Sony integrated stereo amplifier suffers

Hi,
I'm sorry to know that the left channel of the amplifier is not working as expected. I'll be glad to assist you with this. Please try the following steps to get the issue resolved.
If you are not able to get any sound when playing audio from one of the speaker, there may be a problem with your hookup or there may be an incorrect setting. Follow these steps to try to resolve this issue:
Try selecting a different sound mode on the A/V receiver, such as the Dolby Pro Logic II (DPLII).
A majority of cable and satellite TV channels are broadcast using two-channel analog audio. When watching one of these TV channels, only the front speakers will output audio. In order to hear audio from all speakers, make sure to change the sound field to DPLII. This creates a simulation of 5.1 digital audio. If the channel is broadcast in digital 5.1 audio, change the sound field back to AFD Auto to enjoy the digital surround sound audio as it was actually recorded.
If you still have the same problem after changing the sound mode, make sure the speakers are securely and properly connected to the A/V stereo receiver.
If your A/V receiver has an Auto Calibration function, try using it to setup the appropriate sound settings.
Perform a Test Tone operation to verify that all speakers are working.
Increase the volume level of the speakers.
If applicable, try selecting a different size (small or large) speaker.

Try these settings which should resolve the issue. Please feel free to get back to us for further assistance.
Thank you for using FixYa.

Electrical schematics


Wiring diagrams are routinely placed somewhere in the back of the appliance, often behind the access panel, and sometimes inside a small envelope, or rolled up and stuck into a frame channel.

What is the value of resistor R451 in Technics amplifier SU-Z25


If you are in the power supply, are you sure that one is used? 4xx series are power supply designations. Maybe numbers got transposed?
2 ways to approach it.
I am looking at an SUZ22 and an SUZ55, the power supplies are roughly the same. The closest component is R416 which is a 39 Ohm resistor. This supplies power to the flourescent display in a current limitng mode.

The alternate approach is where is it in the circuit? what is "downstream of it"?

If it was a larger 1 Watt or 2 Watt Try 1500 Ohms.

If it is the flourescent display, 39 ohms is most probable for manufacturer inventory purposes. If LCD, try 390.

If the preamp is downstream, it is not going to require a great deal of power, and you may be able to trace a parallel trace off the other channel to a corresponding resistor. If that has been tried and it just traces back to the same point, Try 1500 Ohms.

Also, there is symetry in the amplifier because it uses a split supply Vcc- and Vcc+ Not to mentione the symetry between right and left channels.

Behringer sx3242fx not working .i need circuit diagram .


Behringer will not release schematics unless you are an authorized service agent... however, sometimes you can make do with the few schematics floating around... What is the problem with the unit? They typically use a switching power supply and the schematics of those aree usually similar enough to repair them.

some technics models use hybrid o/p i.cs and when they go faulty shutdown the o/p to both channels. it is also possible that the fan not working can also cause this fault

Hello! I have a problem with Technics SU-V2X


Well whatever is playing up sounds like it might be getting too hot to me. In any case it's something common to both channels. Just have a look on the heatsink to see if it uses a single IC for both channels, they are can cause lots of problems!
The IC might be marked STK with numbers after the letters. That is the part number too for ordering a new one.
