Thank you for viewing. [Product Information] Brand: KIKUTANI Model Number: RMS-10 (Mini Amplifier) [Condition] Power and operation confirmed with an adapter. Everything in the photos is included. Sound is produced, but it seems prone to distortion. It may be a unit that distorts easily, but since I received it from the previous owner, I don't know the original condition, so I can't determine if this is a product specification. I find it difficult to assess the condition, so I'm offering it at a slightly lower price. Please purchase only if you understand this.
