Hi Noel
The basic schematic is correct. However, it depends on whether the amp uses 6L6s or a quad of EL-84s which values are correct for the bis circuit. Mesa's drawings are always backwards with respect to signal input should be at the left and output to the right. I believe Randall drew the schematic as he would see the circuit in an upside-down chassis (Fender style).
Have fun
