Several years ago I was working on a voltage regulator for an amp that would put out 6VDC. I had the regulator mounted right under the preamp circuit board and it took me WEEKS to figure out that the horrible noise I was getting in the amp was due to the placement of the voltage regulator. I moved the regulator to the far side of the chassis and it solved the problem. No noise and super clean DC feeding the preamp tubes heaters.
Why did this happen? Is there anything I could have done apart from moving the location of the regulator to reduce the noise? Was I picking up switching noise? Years later it's not an issue, but still I'm curious.
Thanks!
