Hey guys just wanted to share with you a power supply I made for the BA2018 Linestage project I'm working on.

It uses more modern LM2941T / LM2991T LDO voltage regulators and features an enable option to switch the regulators on and off while leaving the rest of the board powered.

The board size is 160mm x 100mm and is designed to slide straight into the rails of a Hammond 1455T2201 enclosure.

Output ripple noise is very low which you can see in the attached image.

More details about the power supply on my site:

Overall I am really pleased with how this turned out. :)

Thats neat. What will this be used on/for?
Hi I designed it to be used with my BA2018 Linestage project that I am building as a headphone amp which is designed by Wayne Colburn who created the Whammy headphone amp. The power supply is flexible so can be used for a multitude of preamp or headphone amp builds.

I have some boards left if anyone is interested for preamp or headphone amp projects. Looking to do a trade if you live in the US as there's some items I'm after for a project. :)
