    Kenwood KD-550 hinge lid

    My dad gave me his old kd 550 and I love it. It still works great but is desperate need of cleaning. I’ve tried removing the hinged acrylic cover to clean and polish but I cannot get it to come off. I’m sure 35+ years of crud and whatnot have got it stuck. Does anyone have any tricks or anything...

    This week I was wrapping up an AU-717 overhaul and noticed the volume pot was noisy around the 9 o'clock region.

    Here's What Some Seller's "VG+" Looks Like

    Sigh. That was the grading for both disc and jacket. Either they didn't actually grade it, or they were eating a burger and fries while they did so, and then put it on top of the refrigerator for 3 weeks before remembering to list it.
