Power supply power transistors heat sink. These transistors blow very easily, several had been replaced and more were blown when I got it.
A fan blown directly on this heat sink to keep it cool. The device with the red wires is a thermal shutoff to turn the monitor off if the heat sink gets too hot. These transistors regulate the ±43 volt raw power to the regulated ±22 volt used for CRT deflection. They are controlled by the G8360 regulator card ( 2k) .
