How hard is this if you are unfamiliar with power supplies? I've built the ACA but not anything that needs a real power supply.
It's very simple. I used one from chipamp.com for my Pearl II
DON'T put the output snubber parts in it!!
Ok, then, since I've wet my whistle, what about a battery supply build for the Pearl 2? Any out there I can follow a build on? 🙂
Get it working with the Chipamp supply. The Pearl II has onboard regulation. Mess around with batteries later.
Pearl II build


So, here is the embryonic stage of the Pearl II PSU. Each rail will have its own transformer feeding MBR20200 rectifiers then BHC T - net 10000uf caps which in turn will supply the raw to 4 Super teddy regs (I'm not using the on board regs) As it progresses I'll post more.
Apart from the Pearl boards, the rest I had knocking about...Anyone know the size of the Pearl boards? I'm trying to sort the layout before they arrive.
TIA

Thanks.
My build has moved to the Pearl II build guide
