An absolute charming amplifier offering a superb immersive scene where voices sound somehow magical, different than on other amps I had, thanks to its 4 Triode 300B Vintage tubes.

Made only for Japanese market (100V power source), in the price there is also included a step-down transformer 230V-100V (silent), min 550W rating (more than double its rating), so you can use it right away at 230V European plugs.

There are on Youtube a lot of sound samples with this model of amplifier partnering an AudioNote pair of speakers (see below links, just remove the space before the dot...).

This is the first amplifier to be launched by the Japanese TRIODE producer, launched in 1997 under the TRI brand and awarded by some of the most prominent Japanese hi-fi magazines.

Good aesthetical condition, there are some small signs on the lateral real wood panels (these were optional accessories at the time of launch), perfect working condition!
