LochMaster 3.0 is a developers tool for strip board projects. It has useful functions for designing, documenting and testing a board. Therefore you will find features like auto-generation of components lists, a connection test, an editable library with a large number of symbols and components, and many more.In the new version we have made the software more realistic. The new extended library looks almost like real components. Another great feature is the integrated board-editor. You can now create your own boards, if your desired board is not already defined.source

PSU Designer II is designed to help you with the design of simple linear (unregulated) mains power supplies, as often found in tube amplifiers.
