If you know exactly which diode you need you could post that. Would be easier with some specifics.

so its a buzzing noise. are your turntables grounded? some dont have to be. the buzzing could be several things feedback from something around you or the mixer is buzzing cause of to much power. just mess around w stuff your not gonna break it. and what i mean about that is more wires check wires. dont preform open heart surgery on your equptment. sometimes the buzzing means the faders are going i own 3 vestax mixers and on my pmc 17a right before the faders went i had massive buzzing sound.

If mixer is working properly, check the rating of the adapter versus what the unit requires. Some sites indicate this requires a 12 volt adapter rated at 1.2 amps.

I assume you swapped thee output leads as well as the inputs which you di mention, to verify you amps and cables...
The Vestax schematic I have is NOT your same model, but the companies often re-use circuitry. In the schematic I have it appears that the two channels go through two levels of NJM2068L op amps.
In these two levels there is both a master gain control. It is important to know whether the gain control varies the output level of the right, even if it is low. Also in this gain control area is a master balance pot which varies the ratio of the left and right and is CAPABLE of taking either channel to near zero output... IF you have that control check it for sure !!! The pot is a dual employing both an A taper and C taper which is a reverse of the A.
The right tool for troubleshooting this is an oscilloscope, but first an inspection looking for board cracks around the output and pot area is in order.

BUY A NEW PLUG.

I'd try this company:http://www.wdgreenhill.com/ I had good service from them and I live in Canada. They are in Rochford Essex.

There is likely a voltage regulator or a diode burned out in the vicinity of the power supply. If you have the schematic, start at the power supply and work through the circuit to the I.C. Also look up the pinout on the internet for that I.C. With the power on test the voltages at each pin on the I.C. You should not have supply voltage readings on any of the signal pins. This is an indication that the I.C. is also burned out. Use a volt ohm meter with a D.C. voltage setting. Also hopefully your meter should have a diode test function. If not you can still test them with the resistance test function.Here is a link to an explanation:http://www.elexp.com/t_test.htm I hope this helps.

There is a possibility that your plug on the adapter is the wrong polarity. See if the polarity is marked on your mixer by the power adapter jack.

Sorry, since the mixer is powered by a "wall wart" adapter, it is UNLIKELY there are fuses in the unit.

If it is inoperative, then check the voltage of your power adapter. If you by chance connected a wrong adapter, try the correct one. It is possible damage was done in this case that is not so easily fixed as changing a fuse. The correct adapter looks to be a type AC14 which LOOKS to be a 15 volt DC, 500 ma, with negative on the pin.

Likely a power supply problem. Will require service. If uses external pwoer cube, try a replacement of correct rating and polarity.
