    Hello.

    I have had a radio for half a year, and at the beginning everything was ok. Until one day, the radio after a few minutes of playing began to grunt and so warm up that you can't catch it, it's the radiator at the back. The radio literally comes with 10 min. and it rang so much that you can't listen. I went to the electrician and advised me to disconnect the speakers one after the other and check if it would be the same. Today I checked it and it's the same ... It doesn't matter if I have a radio on one or all speakers. I have no idea if the radio is thrown away or the installation fault. I will add that when it overheats strongly, the radio turns down the music.

    Unfortunately, without opening the radio and the meter in your hand no one will help you, you must at least locate the overheating element.

    Obvious signs of end-stage damage. It is probably implemented on some monolithic system. It should be located and the label should be written. Most of these types of systems are generally available at an affordable price. For example: -TDA7388 - AUDIO 4x45W 8-18V 4R 10% amplifier.

    I had an almost identical symptom after improper use of the start rectifier on the site. The monolithic power amplifier was damaged. He warmed up (admittedly not so much) even without an input signal.

    Guess the guess? There are many factors that can affect this. If it gets hot, take it out and tell it where

    I wonder what other factor can affect the excessive heating of the monolithic system and the obvious occurrence of signs of damage - overheating? Monolithic systems of power amplifiers, including in particular multi-channel ones, are particularly sensitive to any overloading and overheating due to the design with limited thermal pad. It is doubtful that a four-channel amplifier could survive overheating.

    So you write that it is obviously the fault of the radio ... I wonder what are the costs of such an event ... The radio overheats on the heat sink at the back.

    If you don't decide and spin it up, you'll never know. You have the receiver in your hands and you can specify the type of system. You got an example of the cost in the previous answer, or rather the commonly used 4 x 45 W system. You can easily enter in the search engine and find prices :D .
