Admiral 19A11 tabletop
In the Admiral 19A11, what's the deal with these rear-panel potentiometers (like Focus) with the nylon shafts and innards? They're all really, really sticky. I took apart the Focus pot to see if it was frozen with gunk or melted. Looks like new. I cleaned it anyway, and applied a little electronic lubricant. It's still so stiff that it feels like I'm going to ruin the shaft when turning it.
 Is there some magical lube that will make these turn normally? On the positive side, it looks like there's some life in the CRT. All I've done so far is replace the power-supply electrolytics and the 6KV-rated caps.
