|The back ground sign says NO FRACKING, as in hydraulic|
I was pondering how I could ever get at the switch connection to de solder and then re solder this. Then it dawned on me. The switch might have a little nut that loosens.
It's a project, as Steven would say, with a sigh. It's a project, I would say, with gusto.
All that gunk is liquified wire insulation that reacted with oil and time. I have three 201s and one has intact, though "dicey" wiring. The third one looks just like this but I think the switch is a bit better, but I am not sure that is saying much.
