(Showa Retro, Working Condition) KENWOOD Power Amplifier A-M70 Made in 1988 Power on confirmed. Operation confirmed. Sound output check upon connection confirmed. Discovered during a cleanup of a rural warehouse. My grandfather used it, and it was installed until the house was renovated. It was removed and stored in the warehouse. It was stored in a place away from direct sunlight and with low humidity, so I think the condition is good (personal opinion). As this is an old product, please consider purchasing if you understand the nature of the product. Please refrain from purchasing if you are overly concerned about minor details.
