RCA K130 RC501a chassis
#11

One lead should connect to the 0.01uF capacitor and the other lead should be connected to ground. You can replace the cap with two polarized electrolytics. You would need capacitors that are twice the capacitance of the original (60uF x 2 = 120uF). I think the voltage from the motor winding on the transformer is something like 24V IIRC. You might double check to be sure. If that is the case then 50V capacitors should be good. Here is a page I found with a discussion on replacing non-polarized electrolytics:

http://www.diyaudio.com/forums/parts/173...ytics.html

They need to be wired back-to-back ("+" of one to "+" of other and connect "-" leads to circuit or "-" of one to "-" of other and connect "+" leads to circuit).

I also found more information on the motor driven pushbutton assembly. It is included in the information on the TRK-12 television:

http://www.nostalgiaair.org/PagesByModel...015848.pdf

I also found the electrolytic in the parts listing for the TV that shows it is a 60uF 40V capacitor.

When I replaced this capacitor in the unit I restored I just happened to find a 60uF non-polarized electrolytic at a local parts store. Mouser has some 68uF 50V non-polarized electrolytics.
