Sounds great on battery but distorted with wallwart
« on: June 04, 2017, 06:50:27 AM »
I built this clean boost (lpb1) and its a great boost with lots of clean gain using battery power, but switch to wallwart and it gets crunchy and more noisy. The transistor is bc548. I know batteries are quieter due to almost zero ripple etc but what should I do? Build in a power supply filter? Im not really sure how to do that.

Measure the output of the wall wart - or use a regulated one like the One Spot and see how it works.
