Korg Es1 power problem....schematic?

Hello,

I've got a es1, and i absolutely love it, so much so that i sold my mpc1000 as the korg was far worked in my crerative process soooo much better.

Unfortunately, during a state of utter twattery, my housemate powered it with a random wall wart and it no longer works.

So...i opened it up to have a look and its clear to see that IC6, which appears to be an SO23 size 5 pin device...such as http://www.diodes.com/zetex/_pdfs/3.0/pack/SOT23-5.pdf

is blown...its really blown...charred.

Does anybody who has access to a service manual or schematic know what this particular component value is?

Any help at all and you'll make me a very happy man, and reduce the severity of the numerous beatings i have planned for my housemate.

Thanks!

surely someone must have something?

Failing that...does anybody have experience dealing with Korg Uk suppport? Are they forthcoming with helpful information?

Generally speaking, Korg support is pretty good, both in the US and the UK -- give them a shout and see what they can do for you.

There may be more than one component that got fried, however. Just because a component isn't black and crispy doesn't mean that it hasn't failed.

BTW your roommate deserves whatever beatings you have planned.

Yeah absolutely. However, I much rather spend 50p on a new transistor than send it away, There is obviously no guarantee it would work but its a good place to start.

There are a few threads with links to service manuals that are now dead. Surely someone must have a copy?
