rca: Ch= RC-501A; K130 Repair of Motorized Tuning

Some tips for repairing the motorized tuning system on the RCA K130 and other similar models:
First I had to replace the AC motor drive capacitor, which is a 60 uF 24 VAC nonpolarized electrolytic capacitor. I used back-to-back (the two + ends connected) polarized electrolytic capacitors, first trying two 50 uF 50 VDC capacitors, and then two 100 uF 50 VDC capacitors. The two 100 uF capacitors provided better motor torque, so I went with those. The insulation on the two wires connected to the rotating split plate on the rear of the tuning capacitor was in bad shape, so I replaced those wires with modern very finely stranded (highly flexible) wire. This should hold up well for many years. After these fixes, the motorized tuning system works perfectly.
