What should I use to fix my radio?
If you’re working with a transformerless radio, make sure to use an isolation transformer as the metal parts might be in direct contact with your AC mains and could cause a serious injury. Use personal protection equipment and good ventilation while soldering.
What can I do with an old AM radio?
If you don’t have one, don’t worry. You can do most of the alignment of the intermediate frequency (IF) and radio frequency (RF) sections with just the existing AM stations you can pick up in your area as test signals. It will come out pretty close.
When do you replace capacitors on a radio?
Mostly ’30s and early ’40s capacitors, with some early 2000 era replacement parts thrown in. I like to proceed carefully, one component at a time until all questionable capacitors have been replaced, then power it up and see what happens.
What causes an old radio to burn out?
Dead electrolytic capacitors in the power supply have killed many old radios, and the coupling and bypass capacitors can cause tubes to fail and coils to burn out. Take a look at Photo 2. PHOTO 2.

Can a car stereo work with an aftermarket radio?
– In some cases, car stereos do not come wired with a 12v Accessory/Ignition wire, making an aftermarket radio difficult to install and work properly. Many Jeeps and Chevrolet systems have a data signal wire that carries a very low voltage signal that tells the OEM Head Unit when to turn on, however; it is not compatible with aftermarket units.
If you’re working with a transformerless radio, make sure to use an isolation transformer as the metal parts might be in direct contact with your AC mains and could cause a serious injury. Use personal protection equipment and good ventilation while soldering.

What causes an aftermarket amplifier to enter protection mode?
