FM/AM radio, model RN-Z500, frequency range 76-108MHz, 525-1650kHz. - Brand: National - Model: RN-Z500 - Frequency Range: FM 76-108MHz, AM 525-1605kHz - Power: DC 6V (SUM-3 x 4) Thank you for viewing. As this is an old item, there are many scratches, scuffs, dirt, dust, and discoloration. The terminals for inserting batteries are broken, so it cannot be used with batteries. I confirmed the operation using a DC 6V external power supply input. I was able to listen to one FM and one AM station nearby. External power supply plug size: Outer diameter 5.5mm, inner diameter 2.1mm, center negative An adapter is not included, so please prepare one. Please note that general-purpose adapters often have a center positive polarity. I can also provide one, so please let me know if you need it. I will purchase it when I go shopping, so it will take a little time. - Akizuki Denshi DC 6V 1A adapter (center positive) ¥660 - Polarity conversion cable ¥550 I do not have a microcassette, so I have not been able to check its operation. Being old, the rubber belts may be broken. REVIEW (Rewind?) When the left-facing button is pressed, the part on the left side rotates. CUE The right-facing button (play/fast forward?) did not rotate at all. The orange REC button remains depressed. I don't know if this is the specification, because there is no tape inserted, or if it is broken. I have described the current condition as much as possible, but there may be oversights. For those who do not mind, for interior decoration, or for parts, how about it? I cannot answer technical questions. This is a junk item, so I cannot provide support for any defects. I will ship via Yu-Yu Mercari or Raku-Raku Mercari.
