SOURCE: My technics amplifier one channel

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 My reference book shows that Technics is connected to Panasonic, but it could be out of date.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.

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.

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.

Technics amplifier su-v98, cuts off at 22-24 desibls


The most common cause of this is defective coupling caps inside. These allow some DC voltage to pass through to the final amp stage. This DDC voltage is detected by the protection circuit and the unit shuts down. This unit will require service. Please note that this should be a simple and inexpensive repair. The cost should be less than $10 for parts.

Do you have a schematic diagram ?
Beeing an old amateur radio technician, that is, working with sophisticated receivers don´t see any problem to help you.
It is my oopinion however that unless I can have a copy of the complete schematic diagram it will be impossibleto start giving you ideas
Can you provide me a coopy of the schematic diagram
And tell me if the amplifier section is working fine and also (very important) if other frequencies, excluding fm are working.

Only 1 channel works for both the A - B selection


If only 1 channel works for A and/or B speakers, you have an amplifier failure issue and the unit needs to be repaired/replaced.

If you have audio in both channels on A, but only 1 on B - then you need to check the connection for the B channel,

Most receivers from the 1980s forward require that to use A *and* B speakers at the same time, all must be connected.
