Using a current limiter, similar to this one:
will avoid damaging any components if there is a short somewhere.

For additional protection, I use a Variac with new circuits (and cap jobs) to form new capacitors gently. Starting at about 40v for a few hours and then add 10v per hour until reaching 120v. It’s probably overkill but I know from working with large caps in photo studio strobe equipment that they work better and last longer if you give them a chance to form slowly rather than just ripping them up to full voltage right off the bat. On the other hand, not everyone has access to a Variac and I sure most manufacturers don’t take the time to form caps so going for it must work fine too. Please let us know how it works out for you, post photos if you get a chance. Good luck and congrats.
