TDA7353 based amplifier for beginner
FizZzyCap:
Hei. Have had a Logitech z-10 for around 10 year and was greatfull for the sound it delivered but lately a static sound has become for prominet while the speakers are on, even when there is no music playing.
It has it, that i'm a total beginner to electronic and aspecialy over my head with a fault search attempt. I have taken an interest for electronic and have some basic material and components with some tools. My current goal is to gut the Z-10 speaker case and replace original circuit pcb with an diy prototype board. Dividen amoung the two cases are a power supply european 240 lead and the other have the pcb, lcd and button with a ribbon cabbles.
So i ask here hopeful for a compete guide on how to take out essential components from an Logitech Z-10 for a TDA7377 based amplifier. If integration of an TDA1517 is possible also, that would be above nifty.

Not sure but may be an GBU6J http://www.alldatasheet.com/datasheet-pdf/pdf/14725/PANJIT/GBU6J.html
Audioguru:
The audio power amplifier ICs you listed are obsolete and are not made anymore. I look at www.digikey.com to see if they are active and in stock or they are obsolete.
A beginner will have a nightmare making a high quality audio amplifier on a "prototype" board because it will oscillate at a high frequency caused by the many rows of contacts and the messy maze of wires all over the place. Buy a kit that has a properly designed pcb instead.

seems a bit advanced for a beginner project. Audio can be a touchy adventure.
FizZzyCap:
Thanks for the replays.
Would agree with that it seams like a daunting task for a begginer, but it kinda buthers me that it is only a static noise and all else seams to works good.
Is there a common way to fault search for static noise? Maybe a compont can be changed instead of gutting the speakers.
Audioguru:
If it plays static sounds all the time then the IC that is not made anymore is defective and needs to be impossibly replaced. Kiss it Goodbye and bury it. Then buy a new model. ::)
