Hi
I just finished building the Bugle. The problem is that it starts distorting after some 10 min of use. This lead me to think it might be a problem with caps. I removed the 220uF elkos (at the + and -, I am using 14 V power supply) and the sound turned out to be similar to what I am hearing after 10 mins use now. Is it possible that the caps start leaking? I cannot see that they could have been destroyed. Should I consider changing to bigger caps?
