Anyone happen to have a service manual for an HP 1331A X-Y display?

I've got a complete wreck of one here rescued from a scrap pile which is 
arcing somewhere between the tube and the shielding - I expect that nothing 
can be done for it, but if I can work out how to pull the tube (short of a 
complete disassembly, but HP of that era were usually smarter than that) 
then I can clean it up and better assess things.
