What to do on used sets?

Some 70's sets like the Zenith CCII need to have the safety caps checked so you don't blow the tripler and CRT, and of course that era will need Pots and tuners cleaned.

Preventive recapping is always an option, particularly in the sweep circuits where the most problems occur. You can prevent a Vertical IC or a HO Transistor from getting destroyed with some fresh caps.

90's and up just watch them till they die then toss em.

I just picked up a Zenith CCII. I understand cleaning the pots, but what are the safety caps and how do I check them? I'm pretty handy around cars and houses but new to electronics so please bear with me. This is one set I actually paid for and I don't want any problems if it can be prevented. Thanks.
