Rael Posted March 22 Report Posted March 22 Hi, Could anybody kindly either provide a link to or supply the Gerbers for the amp and PSU boards? A BOM would be appreciated if there is one available. Regards Rael Quote

Shawn Posted 5 hours ago Report Posted 5 hours ago Time really flies — it's been over 10 years since the KGST first came out. KGST was one of the very first DIY electrostatic amps I ever built, and it's still one of my favorites today. Recently, I noticed that the schematic in the Stax Mafia Google Drive has diverged quite a bit from the latest version of the KGST PCB layout. So, I decided to take this opportunity to redraw the schematic based on the newest KGST layout. Hopefully, this will be useful to anyone who needs a fresh reference. Please double-check the schematic before using it — there might still be mistakes. Component numbers follow the original KGST schematic as much as possible. New parts are numbered sequentially. Changes from the old schematic are marked in red The servo section has been added Obsolete parts like C2240//A1486/2SC1815 have been replaced with currently available ones Attached below is the schematic. Next step: I'm planning to attempt a shrunk-down version of the KGST layout, inspired by @JoaMat great work. KGST_2025.pdf 1 Quote
