TV analyst/cap replacement philosophies

[radotvguy]

I just purchashed one of those B&K analyst units . I am kinda new to tv repairs however i must say its a really nice piece of equipment and it has a lot of functions. Mine its pretty much all original with all test leads and original manuel . Its appears to have all original electrolytic caps still inside . Should i change them ???? I cant wait to learn how to use this . I have seen these unit but never had one before .
