Korg T3 synthesizer

I suspect this is a Switch Mode Power Supply? Korg Technical support may be able to help (+44 1908 857130 in the UK), but quite often these SMPS's are just bought in from various sources, and so there are no schematics or parts information available.

Good luck.

Assuming they are burnt rather/charred than someone has removed them. Some tips relating to gauging what their approximate value was etc on the 3 tips files off my URL below

But if SMPS should tread carefully using a variac plus isolation transformer

Yes, SMPS it is. I'm from Croatia, our local Korg dealer is of no help. I thought if someone have service manual to read those values for me ( SMPS schematics is a part of SM in this case).

Thank you for your answer.

Yes, they are burnt.

Thanks for the link.

If you get nothing here, phone Korg UK service department on the number I gave you - I think that a while ago I had the same problem with a Korg SMPS and the tech there knew which resistor to check and he was right. They may have one there they can have a look at.

Does this seem right ?
