Good colleagues, I brought this speaker which had an A1943 in short and a C5200 also in short, in addition to overheating in the crossover, when testing the circuit without the power transistors and without the speakers the relay activates and deactivates indefinitely without having No audio signal and also the clip LED is activated when the relay is deactivated. The voltages that it gives me are -90v, 60v, -15v and 15v, I have measured resistors and diodes, also must the filters, I need to check some transistors, the pre-amplification and check them and is not leaking
