Technics SA-EX300 Service Manual

Here you can download a fairly accessible manual but in pretty poor scanned version.
If you find any higher quality, especially original digital version if exists, somewhere on internet, pls let me know.
This one is usable, but not an eye candy.

Most interesting is short text about our overloading situation:

OVERLOAD DETECTION FUNCTION
The HIC protection circuit functions if any cord at a speaker terminal is short-circuited or if the unit overeats because of improper operation. At the same time, OVERLOAD scrolls across the FL display. In this state, all keys remain inoperative; if any key is pressed, SWITCH OFF POWER,' scrolls across the FL display. If an overload occurs, Immediately power off the unit and check the speaker connections and venting holes. After fixing any faults, power on the unit again and check for proper operation. If no defects are found, or if the unit remains overloaded after it is power on again, check the circuit for faults.
