    Champagne Face Plate Restoration

    Contact Cleaner 'type' (on Tivoli radio)

    Hi all, I just bought an old but brand new Tivoli 'Model One' radio (platinum series - yay!). I suspect this thing is near 20 years old. Stations come in and play clearly, but... while I'm still dialing in a station, the audio output can be quite scratchy/noisy. The volume knob works...

    Best way to polish turntable dustcovers?

    Whenever I polish dustcovers I always end up with a dustcover that is slightly clearer than before but still has a ton of surface level scratches. I was wondering of there is a way to get it as close to perfect as possible. I currently use 500-800-1000-1200-1500-2000-3000 sandpaper in that order...

    Clean up (and paint??) a Pioneer PL-516

    Hi all, So I just purchased (locally, here in Montreal) an old Pioneer PL-516. It's in good shape, i.e. — it functions well! And sounds great. (I have a Pioneer PL-514 also, that I have plans to fix up and restore — it also sounds really good, but has some problems with the auto-return, etc)...
