hi all im new to this DIY scene and looking forward to building this wonderful amp going to build a 450V version of KGSSHV carbon other than setting GRLV to 15V and GRHV to 450V and amp to 20ma output, is there anything else that i need to look out for? btw i saw a few build in this thread that have the 110V to 230V board, can share the board with me? thanks to kelvin and all for the awesome people here and of course the amp designs
