I just picked up this eq in a lot of equipment and finally decided to test it out. It's a pretty cool, rare piece. Seems to be well built (heavy) and made in Japan. The problem I am having is it producing static. The static is pretty heavy once the unit is powered on and becomes more and more intermittent as the unit is played. The static can only be heard while music is playing, i.e., when I pause the cd, it's dead silent. Moving the sliders and/or flipping the switches has no effect. The unit is pretty old - I'd guess 70's. The gear that accompanied it were Pioneer sx 950, ct-f9191, PL-530, and a 70's Technics integrated, so I'm assuming it was purchased around the same time. Maybe bad caps due to age?
