Evening all, I have been busy over the last few months designing power supplies for headphone amp projects and this one may be of interest to some of you. It's called the Artemis PSU and it's a single rail power supply which can be configured for different output voltages by swapping out the...

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. :)

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.

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...

Got some dual rail boards if anyone is after any? This is pretty much the PSU section of the whammy but with a couple of design changes.

Here is the single rail PSU I built. Working nicely I might add. I need 2 of these boards for testing so I have 8 available. :)

Here are my other designs. First up we have the traditional dual rail positive and negative power supply which can be useful for many projects: I have modified the design from the one on the whammy where by the LEDs on the output are used to provide the regulators with an idle load and there...

Will do. I'll post my other designs at some point in the next few days. :)

Hey all I made a few different designs based on Wayne's power supply for the whammy. The one shown is a single rail positive CRCRC filtered linear supply. This board is already in the fabrication house and I'll be fully testing when they arrive. I have also made a board based on the pilot...

Hi you need to check the ground of the Alps pot. If you don't have one, attach a ground wire to the body of the pot to eliminate noise. Also to eliminate noise at either end of the pot on absolute minimum and absolute maximum, you need to attach 100 ohm resistors to the middle pins of the pot...

Hey guys I have done a review of the SparkoS Labs discrete op amps on my site. Please feel free to take a peek: https://www.audiosy.net/2019/11/21/sparkos-labs-ss3601-and-ss3602-discrete-op-amp-review/

Hi guys, please take a look below for my take on the ifi xCAN portable headphone amp: https://www.audiosy.net/2019/11/10/ifi-xcan-review/

Hi guys Please check out my review of the Burson Swing DAC below: https://www.audiosy.net/2019/10/30/burson-swing-dac-review/

I have decided to do a review of the Topping D50 after using it for a few months. https://www.audiosy.net/2019/10/23/topping-d50-dac-review/ More reviews coming soon!

I thought you would like that one. Also a really nice one is the Analog Devices AD746JNZ. You will not be disappointed. :)
