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!

Good Quality of the File.
You get the normal manual is incudet.
2. Before Repair and Adjustment
Disconnect AC power, discharge Power Supply Capacitors C1702 through a 10 , 5 W resistor to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screw driver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac, to avoid over current. Current consumption at AC 120 V, 60 Hz in NO SIGNAL mode should be 400~1200 mA.
3. Protection Circuitry
The protection circuitry may have operated if either of the following conditions are noticed:
- No sound is heard when the power is turned on. - Stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are �shorted�, or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used. If this occurs, follow the procedure outlines below:
1. Turn off the power. 2. Determine the cause of the problem and correct it. 3. Turn on the power once again after one minute.
Note: When the protection circuitry functions, the unit will not operate unless the power is first turned
