First time poster here :)
I built a CMoy amplifier according to Tanget's schematics. I tried to build it with as exact components as listed on his website.
This was basicly my first project of such sort. I don't have much experience with soldering. This is how the amplifier looks like from the front
and from the back.
The problem is, that the amplifier produces some noise when it is on. I was hoping one of you guys with more experience could help me with identifying the problems.
I did my best to capture the audible noise that is present on each channel. So here are the said recordings:
This is how the left channel sounds like when there's no sound playing.
And this is how the right channel sounds like when no sound.
I also did a recording of the right channel when music is playing. I fiddled a bit with play/pause and with volume control. The popping at the end of the recording occurs when the volume is completley turned off. Here's the recording of the right channel playing music: R channel with music
The noise on the left channel isn't that bad, but the fast popping on right channel is quite audible. What could be the reason for this kind of noise? Defunct cap? Bad resistor? Bad soldering work?
I think it's worth mentioning that I'm powering the circuit with a universal power supply set at 12V. Could this be the reason?
Thanks for your help!
