Blown Caps in 0-30v 0-10a bench supply repair

Ok, so where the positive output is soldered to the board, there is a diode soldered to the same joint, inbetween the replaced cap, and the two white (resistors?).

It shorts both ways, but do i need to take it out of the board to test it? Or can you test a diode in circuit (used both my diode test, and ohmic resisitance functon on my multi, no resistance either way). Also, a resistor, right next to that diode/cap, 1k ohm, is shorted, looks like its burned up, and shows no resistance when measured with a multi.

And i finally found a bit more info, and the brand name for this supply-

From what that thread is saying, these are pos units. If i have spare resistor/diodes of the same rating laying around, i may attempt to replace them, but i'm not spending any more money trying to fix something thats, well, a piece of crap.

Anyway, i'll dig around and see if i can find the resistor/diode needed, i'll update if i can find what i need.

Heres some pics of the diode/resistor-
