I apologize but I’m still confused. C85, R135, and R129 all meet at the last tab on the rail on the picture above, the same tab that begins the original white wire going to the grid resistors. On the opposite side of R129 from that rail tab is one of the negative twist tabs from C79, the twist tab that is also connected to a purple wire in the picture above. Is this the point where I should connect the IBAM poster source (the C79 twist tab)? If so, I also completely remove C85, R135, and R129, correct?
