(Rare Showa Retro Item) National (Panasonic) 2-channel Power Amplifier RAMSA Made in 1987 Power on Checked. Found during a cleanup of a rural warehouse. Used by my grandfather. Removed during a renovation two years ago and stored in a warehouse in a place away from direct sunlight and with low humidity. I think the condition is good. (Personal opinion) He said it was working without problems when it was removed. Current sound output check has not been performed. I removed the top cover, and there was almost no dust. It became clean just by blowing with an air duster. (Since it is an old product, there was some aging.) Since this product is about 40 years old, please consider purchasing it if you understand the nature of the product. Please refrain from purchasing if you are overly concerned about details.
