Pearl 3 Burning Amp 2023

For scale, the (partly stuffed) BA2018 board next to pair of Pearl 3, on 230x330 Galaxy.

Yes, you could run BA2018 and Pearl off Pearl 3 raw PSU. But remember that BA2018 needs to be fed with regulated voltage, so you'll need something to regulate for the BA2018, but that is straightforward.

ACN uses a single voltage, so just use it's wall-wart.

For grins I have assembled on perf board a LM7815 and a Sparcos 7815 3 legged supplies.

Both supplies are operated into a breadboard of the P3 input stage.

The raw supply for both is a TRIAD 18volt DC wall wart. See the attached AP scope and FFT plots.

The LM7815 regulator is much cleaner.

Thanks DT

Orange is the LM7815 regulator.
