Korg Zero 8 Power Supply

Yes, I agree with that, now is the time for you to be brave and plug it straight into the mains, the lightbulb will make the power supply (not incorrectly) think that there isn't enough power to switch it on so it will simply keep on trying to start. If you absolutely must use a light bulb as a current limiter it would need to be big, 500w at least, but as the psu wants about 30w to run a 60w light bulb will only allow it to charge to 160v, which is not always enough to make it start correctly.
Run it for a few seconds at first just to make sure.
Good luck!

Hi there,
I wish to find a power supply unit for my korg zero 8 as mine too is kaput, I'm not up to the task of replacing the capacitors as I have limited experience in electronics. I would like to know where I would be able to find a unit that replaces my psu.

The model number etc on mine is
MODEL NO.: 3B-455XX01
INPUT: 100-240V~,50-60Hz,1.5A
OUTPUT: (1) +5V/2.0A (2) +12V/1.0A (3) +18V/0.5A (4) -18V/0.5A (5)+48V/0.1A

I have tried the sites listed in the earlier posts but to be honest I don't really know what I'm looking for, if anyone can help I would be most appreciative.

Thanks for the quick reply I'm having a look now but I don't know exactly what I'm looking for/at. In the output filter on Farnell do I select 4? As there is no option for 5 (as there are 5 outputs listed on the side of the large capacitor)

Yes I am lost totally, I was hoping that it would be a case of finding the right replacement unit and then mounting it back in and plugging in the two cables again. I do respect your advice and don't want to cause myself any injury is there anywhere you would recommend for repairs?
Thanks

Lol I'm in Hampshire in the UK , Im currently awaiting a reply from http://www.audiorelated.com/ as to weather they can repair it or not

Hey guys,
i just finished repairing the psu of my Korg Zero 4 by changing out all of the condensators of the DC-section of the psu.
For refrence heres a list of the condensators i needed (cost me about 10€ in total):

all of them have a diameter of 8mm, the height isn´t an issue because theres enough room in the z-direction in the psu...

4 x 220uF   25VDC
2 x 470uF   25VDC
2 x 1000uF 10VDC (these ones i mistook for the 470uF because they are really crampend in there, so i needed to order them serparately...)
2 x 100uF   63VDC

hope this helps someone else as well.

Best of luck ;)
