The resistor looks to be a 2w metal film, but could be a fusible type, its difficult to tell from the photo. If its red/black/red/gold it is 2k ohm 5% tolerance. So as youve been informed unsolder one end and re-check the resistance and it should read 2k ohm +or - 10ohms, if its ok put it back in. The electrolytics are cooked, replace them both together with the correct diodes, then check all the other components in the power supply and if they are ok you should have a working unit. You havent said where you are based but if you cant obtain 2k 2watt just use 2 x 1K ohm rated at 2watt connected in series.
