I have Audison LRX 1.1k with this problem.When i connect 12v - and+ this resistos from pictures start to increase temperature without any stabilization..If i remove CPU pcb temperature stop raise.I verified all transistors from pcb and seems ok.This resistors must be from aux supply 15v..This problem happen even if REMOTE is or not connected.If somebody know better this type of amplifier please leave here,diagram,message!😕
