    Don't forget that there are set screw locks for the resonator mirror adjustments in the center of the knobs.

    The schematics for the head would be great. I don't mind paying for them if it's not too much.
    thanks

    The schematic for the head is the final one in Steve's post above. It's the same in my manuals, but mine says "serial number 118 and above".
