・This is the ONKYO INTEC 205 series integrated amplifier A-905FX. ・It is the model just before the final model of the INTEC 205 series. It underwent a complete model change from its predecessor, the A-905TX, and became a digital amplifier. ・For this listing, the speaker relay has been replaced with a new one, the interior and exterior have been cleaned, and the rear terminals, which were tarnished and made it difficult to insert cables, have been polished one by one. The terminal polishing is not perfect, but it is at a level where there is no stress when inserting cables. ・After the above work, the following checks were performed: ① Sound output check by connecting to a CD deck and tuner. ② Tone control (TRIBLE, BASS, SUPER BASS) check. The sound quality is subjective, but you can enjoy clear and powerful sound. ③ Subwoofer output check by connecting to my subwoofer SW-5A. ④ Basic operation check with the remote control. ⑤ Sound output from each input. ⑥ Long-term operation check (approximately 7-8 hours). ⑦ Recording and playback of Hi-MD by connecting to the separately listed MD deck (MD-105FX). ⑧ Processor mode switching and connection check with the equalizer (image 7). ・There are some scratches due to the product being used. Please refer to the images at the end for scratches. ・The listing includes the main unit and the remote control RC-614S. The remote control has some scratches. Please prepare batteries for the remote control. Two AA batteries are required. Manganese batteries, which are less prone to leakage, are recommended. The equalizer in image 7 is not included in the listing. Since this item is also listed on other sites, please comment before purchasing.
