Crate Vintage Tube 50 Head Schematic needed

[caverat]

I searched the Crate site and what comes up is a fixed bias amp with speakers (Mine is just the head) . It also appears to have cathode bias with 4 EL84 Outputs, (unless there is some hybrid circuit). I need a schematic showing the cathode bias amp.
