No, I don't want the schematic. Yes I know it is 4 12AX7's and either a half dozen 6L6/6550's for 400 or dozen 6L6's for 400 plus. What I want to know, looking down on it with the controls facing me, what are V1 through V4 locations. There is compelling logic for 1-4 being right to left and for left to right. Anybody know? FYI, V1 and V2 are the preamp and eq section whereas V3 and V4 are for the driver circuit for the mess of output tubes. It's the same layout for the 400 and 400 plus.
