This is a mid-range stereo integrated amplifier from 1988. Cosmetic condition: There are slight scratches on the front panel's top surface and the chassis bonnet, but the condition is good overall, including the front panel, knobs, push switches, chassis, insulators (feet) made of foamed rubber, and input pin terminals. I confirmed that line inputs such as CD are output with the main direct on. Regarding the phono input, I have not checked the operation by connecting a player, but I judged that there is no problem because the residual noise of the equalizer increases and decreases smoothly and consistently according to the rotation of the volume VR. When listing the item, all functions were working without any problems at first, but a malfunction occurred where sound was not output from one channel when the main direct was turned off. I cannot determine whether it is a contact failure of the main direct switch or a contact failure on one channel of the relay that the main direct switch controls. Due to the age of the product, unexpected failures or sudden malfunctions may occur, so it is listed as a junk item. Please use it for repairs, parts, etc. Please refrain from bidding if you do not understand the concept and value of junk items. In terms of sound quality, it is a high-definition, glossy, all-around type with no noticeable flaws, and it is a modern high-performance amplifier with a lot of cost put into it, such as large transformers, electrolytic capacitors, and heat sinks.
