LA502 - PCB 1.2->1.3 C5 47p cap
Hello,

I bought the LA502 PCB 1.2-Version and already did the mod for reducing noise.
In addition to that mod, there is an additional C5 47p cap at the input part of PCB 1.3 who's been missing in PCB 1.2.
Is it also recommed to add this C5 cap?
What exactly is the benefit of this cap in addition to the two 470p caps?

thanks!
best regards,
Guido

No, not necessary.
This cap ensures better Common Mode Rejection Ratio (CMRR) in case the 2 caps differ in value.
