It's been 13 years, and it's been in stock for the first time in a while! 39 transistors, 25 transistors have been replaced, and maintenance has been completed, including volume and switch contact polishing! The final Usmarantz pre-main amplifier. This product pursues low TIM (transient intermodulation distortion) and transient mixed modulation distortion. It is rare for this model to arrive, so I think it would be difficult to find one that has been maintained. Why don't you take this opportunity (Daiki Goto)
