This is a awesome quality scan of the original Service Manual for Technics 8099.
Contains the circuit diagram, PCB layout, adjust/tune instructions as well.
Since this is my first buy here, i'm really glad! This site do works as intended/described, it's definitely not scam!
Мои рекомендации! Все мануалы настоящие!
Very nice and real Service Manual, I didn't thought it actually exist in the real world at all.
