DENON Denon Audio Tuner TU-7.5S AM/FM Tuner

◆DENON TU-7.5S AM/FM Tuner◆

This was found in the audio room at my parents' home.
It was apparently purchased a long time ago by my grandfather, who was an audio enthusiast.
He was particularly passionate about FM air checks, recording them onto cassette decks to enjoy.
Although it's a bit difficult to see in the photos, it appears to have been used quite a bit, so please be aware that there are some scuffs and scratches on the top panel and side panels.
(The front panel is relatively clean. Please check the images.)

Since it was made in Japan, I thought it might still work normally. I turned it on earlier, and it powered up fine, with the LCD screen lighting up clearly.
(I was also able to change bands and frequencies.)

After that, I connected it to an amplifier via the line out. White noise was present, but I couldn't receive any radio stations.
When I asked a friend, they suggested it was probably because nothing was connected to the antenna terminal. However, I have absolutely no knowledge of audio tuners and couldn't figure out anything further.

This is all I was able to confirm, so please consider this item after acknowledging the above.

Free shipping.
To all audio fans, thank you for your consideration.
