Question Smoothing Cap = Noise Source?

Hi friends,
I'm finishing a pcb for a tube guitar amp
and I used some smoothing caps and power
line which are a little near to gain pots. Are
these smoothing caps a potential source of
noise i this position?

Take a look at the pcb please:
Marked in GREEN - Smoothing Caps
Marked in RED - Gain pots outputs

Thanks a lot for any info

Looks like these are a long way from the rectifiers, so there won't be much noise at all. The first cap after the rectifier is the only one carrying much ripple voltage or current.

Hi Tom,
You are right, I tried to put the
rectifier at one end and the first two tubes and
tonestack at the other end of the pcb, following
with the power line across the circuit.

Thanks a lot.
