Hi!!
Im just received a second hand MP573 (I have other three), and after compare them with "Smaart", the last one has a -6dB drop across the entire frequency spectrum, and that difference remains even when modifying the gain or the output potentiometer.
Where should I start looking for the point of failure?
Thanks in advance
Regards
Sergio
