Please someone explain what is the purpose of R4, R5, R6 and R7 in the attached image of a power supply;
Iam asking because I have a power supply with similar configuration, with 3 power transistors at the output but without thos 5W 0.1 resistors. The problem is that one of the power transistors seems to work harder(gets hot) than the other 2(they remain lukewarm). Do those 0.1 restistors could make any difference in balancing the output current equally to all the power transistors;
