Re: Repairing Plastic Coils

The lid is held in place with the tar alone, so it’s easily prised off with a putty knife. The condenser needs to be replaced since it’s the wrong type, being too low in value, and not of the high dv/dt type required. I reattach the lid with silicone. The electrical characteristics of these coils is...

Those older capacitors in the photo are .047uF. That is way too low of a capacitance value. It should be about ten times that; i.e., .47uF. Aside from that, the dv/dt rating is most important. This is the rating of how quickly the voltage across the capacitor can rise in a given amount of time witho...
