I'm hoping someone can help me locate information on these: I ended up with a quantity of Ampex Catalog 6445 sound preamps (tube), which I've been told were probably originally usd in early Cinemascope or Todd-AO systems. Does anyone have schematics or other info on these? Does anyone have a need for them?
