Pioneer C-90 control amplifier
This is a high end pioneer c-90control amp, the bad- it seams like the tone control switch is bad or going bad it will come on and go off sometimes, I just don't use it , but oh well, there is a small scuff right above the volume knob, see pictures! The good, it sounds amazing ,very clean deep base crystal clear highs , really pioneer went overboard in designing this preamp , you can google the facts about how well this was built with the m-90 amp, it weighs about about 27 lb and I'm the second owner, the original owner bought this overseas while in the air force in 1989 brand new, I got it in 1995 and had it since, thanks
