Hello,
I've recently built my first preamp using boards from Elliot Sound. Currently I have P05a and P88 mounted in a wooden enclosure with an ALPS pot. I decided to use a 16VAC plug pack for input to the psu board. My question is this:
Why do I hear annoying snaps, crackles, and pops when no source is playing? I also hear it while playing source through the preamp, but it is of course less noticeable... sometimes. What is this noise? It is intermittent and not predictable and very unwanted.
Links to the pcb's I'm using.

More information and pictures are available on request of course.
Thanks!
