This unit has worked very well since I have acquired it. I have not used the MC function but it works fine for the MM section of the Phono function. All lights work. There might be a little scratchiness when using the volume, but that works out when twisting the knob. Probably a good DeOxit would take care of it. On the back panel there is a switch for connected or separated (for the pre-amp and the main amp). There was a locking plastic piece for th...is but it was not there when I bought it. Its absence does not affect the amplifier's functioning at all. Also absent is a sticker with a serial number. It came to me that way. Why, I do not know, but I want to reassure you if you are looking for it and can't find it, it is not there.
I will double box it for shipping, NO confetti or useless wadded up newspaper; I will only use very good packing material. This is a great unit by Sansui and it is heavy.
Shipped only to the lower 48 continental States.
Please contact me if you have any questions. The price set is the price. Thanks for looking!
