[Milsurplus] Oil-Filled Caps (BC-779)

[Carole White-Connor]

    I'm working on a power supply for a BC-779. It has the original
oil-filled filter caps. I have yet to fire it up. However, I intend to
use this BC-779 and power supply on a regular basis for SWLing. The
receiver is a great-performing set.

    Here are my questions:

    1. I understand that these oil-filled caps are more reliable than
electrolytics of the same vintage. However, what is the consensus on
whether they should routintely be replaced?

    2. How can I test them? I do not have a cap checker. I will have to
use a VTVM.

    3. These caps are rated at 600 WVDC. Is that overkill? What would be
the recommendation for the voltage rating of replacement caps?

    As always, thank you for your help and guidance.
