Having a great time doing the mods and looking ahead the the upcoming videos in the project. Got the R8 BOM parts sorted out. Just watched the video on tuning the GNFB and I see the R8 BOM has 2x 24K resistors and a recommended 330 Mica Cap. I'm not at my work bench right now, but where are these parts located in the amp? I assume they are on a PCB or several somewhere. It just was not shown in the video.
