Rebuilding an old AM radio

Step 4: Radio is now working correctly

By this stage I have replaced the filter (electrolytic) capacitors and the paper and wax covered capacitors, replaced the power cord, and fixed all wiring that needed insulation.  Upon powering the radio up, it now worked fine.  So, my next step was to tackle the case.

Many restorers prefer to leave the original electrolytic capacitor cans in place. It looks nicer and provides future restorers the ability to match the original capacitor values. Just remember to disconnect all wiring from the positive terminal(s) of the original cans.   If the original can is mounted on an insulator and/or has a cardboard cover (like the ones in this Zenith radio), then disconnect the wiring from the negative terminal(s) as well.

A few restorers try to hide the mylar capacitors inside the original paper capacitor tubes. To do this, scrape off and set aside as much wax as possible. Using a small x-acto blade, carve out and dispose of the paper-and-tinfoil guts. Slide the new capacitor into the empty tube. Soften and re-apply the saved wax using a flat blade or paint brush.
