hello that such greetings from caracas venezuela, I am writing to you by this means and since I have a doubt, I recently uncovered my panasonic stereo radio to clean it since it accumulated a lot of dust, and in that procedure it took place to take off the fan to clean it with a brush but do not pay Attention to its initial position and it turns out that now I have my doubt if the fans in the stereo radios work by taking the air out of the stereo or taking it out of it. first of all, Thanks

Hello Friend. they work by taking the air out of the equipment to get the heat produced by the amplifier of that stage of audio output. Cheers
