Fully maintained, including deteriorated condenser, vacuum tube replacement, volume dismantling and cleaning! The fourth model in the 38 series, the successor to the FD. The sound with a good view not found in the early Luxman models is attractive. Of course, it is compatible with TANNOY, but it is also compatible with speakers that have a hard sound, such as YAMAHA monitor speakers. Rust is floating (Daiki Goto)
