Oh, yeah. No guts, no glory! Smoke test is the best test. Double check your wiring, look it over carefully. Check once, check twice, then plug it in and throw the switch!(But shield yourself from the capacitors, no kidding. If something is going to go wrong catastrophically, it will be the capacitors. Resistors can smoke, and so can coils. But capacitors can explode if power ratings are exceeded or polarity reversed.)
Now that I've boosted your confidence, throw the switch!
