Good afternoon friends of the forum, greetings. This time I am addressing you to tell you my case with a Chinese amplifier MKV Model AV.1351 in the main chassis says AV-1251 AMP. PCB This device does not activate the relay and measuring the pins of it I realized that there is no voltage I have changed some components even marking according to the tester that they are good but as some according to the time I have working with these devices I know that they can mark well when in They are really damaged. Anyway I hope you can guide me with this problem. The audio transistors are good and no other component that can give me at least one signal of failure is heated. Waiting for your help I say goodbye and thank you very much in advance.

It is likely that you are missing a supply voltage or that you have an open resistance

Eliezer keeps track of the relay that will take you to the source.

I commented that the fault was a resistance of 220ohms1w that feeds the relay but that resistance did not have it since the device comes from other hands and they had taken it out but it was not clear that this component was missing. Thank you very much for your help.
