I purchased this new in 1970 the K-6002 pre amp and the 6107 4X12 with 2 horns powered cabinet.It was only used once on stage with my high school band and then stored ever since but with regular powered up use around once a year. It works and sounds like new and extremely powerful with only a small issue of the lead channel treble tone button has a slight hiss when turned up fully. I am hoping someone can help me locate a schematic as my repair tech wont look at it without one.

These are frankly rather well laid out, easy amps to work on. While I might suggest cleaning the contacts and the pots, due to age and you mentioning "hiss" it's probably a dried-up capacitor and you'd be well to replace all caps as they were never designed to last 40+ years. Non or minimal use is the main killer of them as well. There may be schematics on ovationtribute.com but if not there, I'd find a tech that has vintage solid-state knowledge and they should be able to suss it out easily.
