Old caps can contribute to it, but it's just the gain amplifying a very small amount of noise if I understand what you are saying.
Its a pretty audible white noise, probably from the gain. Unless turned all the way up, to there there is no resistance.
I just leave the volume all the way up to avoid the noise and use the source to control volume.
I would like to find a way to bypass the bass and treble Eq. And run this little amp as a straight forward amp.

There's the schematic. Find the power stage input trace and solder a shielded wire from those to rca jacks. But don't do anything that can't be reversed.
I have the schematics,
Just jump the EQ board input straight to amp. This will also probably eliminate any unwanted gain/distortion from bass/treble and volume. Giving more of a flat response
