I am only search for 5 Minute, by it in 5 Minutes to and get ist in few ours! Best i found in the Internet and my Amplifer is repaired as well! Thank you
I found the manual to be clear concise and complete. It was of immense assistance when removing the unit as the unit was over 22 years old and the wiring diagram was unobtainable from the manufacturer. The exploded drawings were clear as were the instructions and labels.
I will highly recommend this seller. They are honest, accurate, fast and responsible.

2.2.3.7 SCREEN & FOCUS SHORT CIRCUIT PROTECTION
Above circuit is used for protection against screen & focus grounding. Basicly the base of PNP transistor Q609 is connected to screen&focus potentiometer of FBT, in another words FBT focus pack is connected to ground via R654. The voltage at the base of that transistor is normally higher then the zener voltage at the emitter. When any short circuit occurs at focus or screen the base voltage is decreased to a value lower then zener voltage, that forces transistor to conduction and trigers another circuit which will force UC to protection mode. In protection mode LED becomes RED and remote control does not work.
