Hi everyone ,
I had to "rebuild" my F6 lately ( change the output ) and give the psu more capacitance.
it turns out that the 2nd harmonic is higher than before , x 10 more , especially in the high , what could cause such rise ??
thanks for your idea
I made an comparison with my other amp , so speakers , Dac , cables , are ok

Yes , about the same on both channel , worse at the right channel .
i check several time , solder joint , components , connexions , and so on .
it's only the 2nd who is high, all other harmonics are low as before .
how to check the transconductance of an output at work ?
