Hi, so on amp B, I replaced the 90.9 and the 431 on both the nine pin socket and the board. The tube is not red plating anymore. I'm glad I asked about stocking up on Parts because I should have checked that resistor. Maybe that was the issue thank you for all your help. Here are my voltage readings for amp B and A
