DescriptionThe output may not be stable due to many defects such as poor contact in the parts to be operated, although it is possible to produce the same sound quality. VOLUME, BALANCE, BASS, and TREBLE worked. There may be slight buzzing.SPEAKERS, TONE, and LOUDNESS switches also worked. The POWER AMP DIRECT OPERATION and INPUT SELECTOR switches can switch inputs, but the contact is poor, and when turned, depending on the contact condition, either the left or right sound may be cut off or the volume may be unstable. The SOURCE POWER DIRECT and TAPE/DAT PLAY switches also have poor contact. The left side volume is often weaker due to poor contact. Although the correct audio can be produced, please understand that this is an as-is product, as the output is often unstable due to component failure. There are some strong stains on the surface of the knob, and around the knob there is some writing on the surface by the previous owner. There are also stains and other dirt.The CD input terminal is damaged at the connection and cannot be connected.The sides are brittle with peeling of the surface material.The exterior shows a lot of external damage and stains, and the condition deteriorates with use and age.
