vintage receiver pioneer sx-1080

Description

vintage receiver pioneer sx-1080.
In good overall condition but has a weak left chanel there are a few techs on ebay that service these vintage recievers and it can be refurbished and greatly increase the value of this unit. I have had this unit a long time and was in storage from my last move . when I pulled it out to clean it up to sell it and check function was when I noticed the weak chanel. Im sure its just a resistor or diode maybe a capacitor that is leaky but Im not a tech. So Im not digging into it . most likely a simple fix being a vintage unit, and things were just made better and made to last back then check out my other listings Im selling off a bunch of vintage gear. Thanks for looking. Item is very heavy shipping is expensive.
