I have a rare Vintage Phase Linear Model 1100 Series 2 Parametric Equalizer that I would like to offer in a trade for a set of RS-7s.The EQ is in excellent condition and the speakers should be too. If your not familier with this high end unit, it was built in 1979-80 and sold for $600 then. This one will blend with your Cornwalls AWESOME! Lets work it out.
