Hi guys, As the title of this tread shows I`m having trouble with my new amp. It`s my first amplifier made by me, so I`m beginner and looking for some answers to prevent happening this again.
Here is the schematics I used to made it: 4x15 Watt quad audio amplifier
I made just stereo.
I made it 2 times, 1st time it didn`t worked, because I bought that 4 2R2 resistor, but one of them was just R2, and I didn`t observed. I tried everything I thought may be the problem, because when I turned on one of the speakers not worked, just pulled out the membrane slowly and after about 1-2s it stopped completely. I bought one more ic because I thought that was the problem, and when I demounted the parts from it I saw that r2 thing and my father said that can cause the problem.
I started again, and made again with the same parts, I just used 4 similar resistor, and I when I started it worked, but one of the speaker was a little more quiet, but it worked about 2 minutes, after that the quiet one just stopped working and became so stinky, so I think is burned, but the other one worked correctly. I used the specified parts in correct places, and I used speakers from car, so I don`t think the speaker was to week, or what... I think some of recycled parts was damaged, some of capacitors because that is that I can`t check, but I have no idea which one. or the ic was bad... that I can`t check either.
Somebody can help me to repair my new amp at least?!...
