DIY supplies

The community aspect has always been the cornerstone of this project of mine so I routinely sell a number of the custom items that make up my amps.  Mostly this is the custom circuit boards that I’ve designed over the years, ranging from KGSSHV board sets down to the small circuit boards used on the power switches.

Feel free to contact me at if there is something you are looking for.  All prices in US dollars (USD).

A partial kit to build a +/-450V version of the KGSSHV.  It contains the KGSSHV boards, transformer with mounting hardware, 12 2SC4686A transistors, 4 2SA1968 transistors, a matched quad of 2SK170 jfets. two LT1021-10 voltage references and Teflon Stax socket with mounting PCB.  This covers most of the hard to find parts for the project.  I will also supply a BOM to make ordering from Mouser much easier.

Price: 460$ plus shipping
