I have for sale a rare, near mint Pioneer SX-7730 receiver. I have never seen another one, other than the one I own.
Condition is incredible.
Except for one or two very small blemishes, you'd swear you were standing in the Pioneer showroom back in the 70's. Electrically, everything functions perfectly - all lights, switches, knobs etc. No scratchy-ness in the controls at all. I have tested every function of this receiver, with the exception of the phono. I do not have turntable, so no way to test it, but I do not have any reason to believe it doesn't work perfectly as well.
