Denon TU-1500

Found this little forgotten gem in my storeroom last month.

The TU-1500 is a light and compact digital AM/FM tuner. It was previously purchased with my AV amp, the Denon A-1D. The nicely presented TU-1500 has the usual bells and whistles normally found on a Japanese tuner with bonus of alphanumeric labeling for stored radio stations. Buttons are a bit small and close together though.

In stock form, the TU-1500 actually sounds quite nice but repoduction of the mid was a little rough round the edges. HF and LF were decent.

Recapped in the past as it had much hidden potential. Not many caps to be replace as the motherboard is simplistic when compared to tuners like the Audiolab 8000T and Sansui TU-D99X. Default caps were Denon (naturally!). Most of the caps were replaced except the big yellow EC, a brown poly and 2 green gumdrop like Japanese non-EC cap. Caps used were 2 Wima, Panasonic ECA in the PSU section, Rubycon and mostly United Chemicon EC on the rest of the motherboard.

How does the recapped TU-1500 sound?

The recapped TU-1500 has a very nice realistic presentation with details to match! You can almost consider it a Audiolab 8000T with a more aggressive presentation - making it very nice when listening to stations playing Indie, rock and the alike!!! The presentation has a light bias towards the mid but in a pleasant manner.

Removed the 2 screws from the rear of the cover as the TU-1500 runs quite warm. Since it has ventilation holes on the bottom of the unit, I though this may help provide an outlet for the warm air from inside the unit. It does run a little cooler without these 2 screws.

  1. Hey - what kind of FM antenna are you running? I can't seem to find a converter to go to an F-connector for my TU-1500. Any suggestions would help.

    1. Was using the building's common antenna via wall socket. Alternatively you can try this eg http://myoldvintagehifi.blogspot.sg/2015/09/diy-better-indoor-fm-antenna.html
