Electrolytic recapping of a 5-303W?

[Jonathan]

In this Sony portable transistor set, does this need to be done? The top of the screen is wavy, the contrast and brightness are way out of wack, and when I first turn on the set I get a buzz from the audio, then it goes away. I plan on replacing every electrolytic and the full wave bridge selenium rectifier. Should this brink it back to decent operation or are there things I should check? Channel 3 comes in super sharp from my satellite receiver, so the IF section is probably still in alignment.

Thanks.
