HELP lectrotech v-7 vectorscope

[snelson903]

last week i got a vectorscope off epay for 10.00 ,it looks like it was never used much i even have the orginal box with it ,i tested it out and it worked only on color input ,so i went through it and found a dead shorted .05 cap now everthing works but everyone over the years must have tryed to adjust every pot and cap in it, im hoping someone here has one with the manual and schematic so i can get it all adjusted right and recalibrate it .thanks
