Я думал дорожки погорели или кондеры, а там маломошные транзисторы типа так сверкали... Но на них нет следа прогара! ??? Что за фокусы???? Но краскопульт конечно у вас самый любимый предмет...

      Blindly switching on the amplifier without first cleaning and checking essential components is unprofessional and can lead to massive damage to the circuit board and the previously intact components. Before anyone gets upset about the criticism: I have a master's degree in radio and television technology and 45 years of professional experience in the field of audio-, video and power-electronics in the areas of service, production and development, I know what I'm talking about

    The nice orange peel texture all over the amp really adds character. Permanently encasing years worth of grime beneath the paint is a good idea for future archaeologists to study when it’s dug up years later. The clear coat and paint really seal in the dirt and grime for future studies. Prep is the key to a nice paint or clear coat.
    If you’re not going to prep at least wet sand.

    Hello. If you turn on the amplifier for testing, I advise you to turn on the amplifier through an incandescent lamp connected in series with the amplifier. If the amplifier is defective, the light will illuminate and protect the amplifier components from fire. After repair, the first inclusion must be carried out through an incandescent lamp, so as not to re-repair and understand that the amplifier has not yet been repaired and there are problems in it.
