This is a KENWOOD K-270 (G). I purchased it 25 years ago. When using the input selector knob on the front left, the input may switch automatically, so I have been using the remote control for input selection. Because of this, I selected [MD] for analog input, which can be switched via the remote control, instead of [AUX]. [Functionality] ◆ Amplifier (Class A Mode equipped) ◆ CD playback ◆ Analog input ◆ FM/AM tuner [Repair History] In 2011, I sent it to Kenwood for repair, and they mitigated the issue with the input selector knob (they didn't have replacement parts at the time) and replaced the CD player's pickup. [Included Accessories] Remote control Instruction manual [Notes] Sound does come out properly, but please understand that this is a junk item because the input selection may become unstable depending on how it is operated. The CD currently plays without skipping. - Brand: KENWOOD - Model: K-270 (G) - Color: Gold - Connection Terminals: Analog input, speaker output - Volume Adjustment: Analog volume knob, remote control - Design: With wood panel - Power: 100V
