Refreshed and maintained, including volume, selector dismantling and polishing! YAMAHA's heavyweight premain amplifier. The low frequency range supported by a good quality power transformer and the clear sound typical of the original Yamaha are attractive. It has an MC phono core, the pre-main part can be separated, and can be developed into a separate one. I have sunburn in the wood cab outside (Daiki Goto)
