I wouldn't use that green capacitor...nothing wrong with them but, as stated above, only 50V which is nowhere near high enough. You need 400V rating or above. There are some very good polyester types available on eBay at 400V or 630V which are ideal and not expensive. The 220 ohm looks like a 2 watt type....don't be tempted to use a lower wattage in this position.
