Picked up a 1976ish Panasonic RF-1080 and have restored it to working condition with one glitch, the FM band has "noise" when tuning between stations.
Not a static like sound, as best as I can descibe it a "crackling" sound. It pops up and moves around different areas on the dial. Could it be dirt on part of the tuning capacitor vanes since it's not across the entire dial? It's a ganged polyester film unit with AM tuning also and that band has no problems. What type of cleaner might be best for this type of cap?
Where might one still find a service manual or schematic? And where does one find a large selection of replacement knobs and antennas, this radio has missing/broken parts which I'm sure Panasonic can not help me replace. - JC
