If it didn't go bang with bulged caps then it won't go bang with good ones. Stick it on the mains, it will work.

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! |

Fired it up today with the new caps and it worked!
No distortion on output. Sounds good. Joe

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.

I had a look on the net for a suitable replacement for this power supply but I had no luck. Korg just said that the product is discontinued. Maybe one of their distributors or service centers might have one??
Farnell have quite a range of switch modes to choose from might be worth having a look there.
Let me know if you find one would be nice to know for future reference. Best of luck! Joe |

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)

I'm sure you would admit to being a little lost with this, As these have dangerous voltages on them I would not recommend that you go any further on this repair yourself. There are plenty of repairers out there who will be happy to either repair or replace the supply for you far cheaper that replacing the unit after you have been unsuccessful and blown it or yourself sky high.. |

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 |

That depends on where you are (or which country you are in for that matter) If you update your profile I'm sure that someone will be along soon... |

You can put it in the post to me if they can't help you, I don't charge their £60 per hour either...

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 ;) |
