Pioneer out of mothballs.

On tuner dial knob I'd use DeOxit F5. It's a lubricating formula.

That's what I used. Thanks. Now if I can get better FM reception I'll be a happy camper.

It has nothing to do with better FM reception.
For that you may need external antenna.

I always had an outdoor antenna since I bought my SX-1250 new in I think 1976. Then sold that to make way for the SX 1280, saw no reason at that point to purchase the SX-1980 if you familiar with those models. Lived in Bklyn,NY reception was great there. Then move to another NY borough again, no problems with an Archer Fm antenna. Now I live just out of NY in NJ & my reception is only fair at best. Inline to NYC to my home are obstruction like power pole & NJ transit, which has an overhead power line to power the Train. Installed are an Magnum Dynalab - ST-2 FM Antenna with an 36 db FM signal amp. I stream internet music thru my computer w/Creative Sound blaster sound card to my Marantz 7702 ii via SPDIF, finally out to my B&W 804/803. Steaming music thru my comp sounds way better then just out of the Marantz. The music from that Marantz apposed to the Pioneer is no match by any means. Also the SX-1280 feed my Klipsh Heresy ii. This is why I'm trying to connect the Pioneer. :(
