Thank you for viewing. This product basically works and is usable, but - There is some crackling in the GAIN and LEVEL controls - There is a lot of peeling of the exterior paint Therefore, I am selling it as a junk item. It is a set of the main unit and an AC-AC adapter. The AC adapter is not a genuine product, but a substitute. As this is a well-used item, there may be other undiscovered defects. Please understand and accept that this is a junk item and that it is non-returnable and non-refundable before considering a purchase. Immediate purchase is OK. I will ship it on the same day of purchase if possible, or at the latest, the next day. Thank you.
