Kevin retired from Northwestern Univ. (the .edu links) a few years ago, so those links are no longer valid. The Stax thread will provide google drive links to the board files and other documents.
For a Dynalo, you will want +/-20V for the GRLV. There are BOMs for the GRLV posted in the thread. Sorry, but we don't provide build guides, etc. here. Going thru both the Dynalo and the Golden Reference LV threads should provide you with all you need to know. Build the GRLV first, and test it unloaded to make sure it is performing properly. Pretty easy build. And I would stay out of the and now for something completely different part 3" thread for now. The Dynalo is a very good amp. Not sure what phones you are intending this for, but the CFP 2/3 is a very good amp.
