Welcome:
Get a schematic of you set first.
You're going to have to replace just about every capacitor in the set to make it safe and enjoyable. There are three kinds of capacitors, the electrolytics, (have polarity, larger values, like 16 Mf, 25 Mf and a voltage rating) and the smaller wax covered ones (like .01 Mfd, .022 Mfd.), and the mica capacitors (100 mmf or pf, for example.) Count on replacing all of group 1 AND 2 before playing the radio again. You should also invest in a digital multimeter to measure the resistors and replace any that are more than 20% off value. Old resistors ususally creep up in value, sometimes double their nominal value.
The fact that it still plays at all is a really good sign. But at this point it is a time bomb until you at least tackle what is mentioned above.
Lots of help available here, just ask. Take your time, it's going to be a long winter.
