Issue resolved

I resolved by replacing the floppy drive with a floppy drive emulator. First I had to instal a convertor, found on eBay SFR1M44-U100K, floppy belt Matsushita EME 216KR adapter. About £35 shipped from Germany. This converted the flat blade cable to a pc type connector plus power connection. Then the ...

iX300 floppy drive format

Hi everyone, the floppy drive on my iX300 reported “no disk in drive”. When I opened it up I found the drive belt had perished. I found a flat belt that fitted. I had to remove the logic board so I could get the belt pass the sensor. After that I again tried to format a disk. It ran for a few sec ...

Update

So when the scope arrived I found good signals on audo left and right and same on the headphone paths. On the speaker paths I could trace the right audio from R74 through the EQ chip into the amp chip and out to the connector CN6, but the left speaker signal stopped at R75. I have now removed the ...

Replaced Amp Board

So I managed to get hold of a replacement Amp Board but the vendor advised that it was only producing sound on one speaker. I installed it and sure enough only right hand side speaker is working. However both Audio Out channels are working and left and right headphones are good. Looking at the ...

Ouch! The bad news, as you've already found out, is that replacement boards aren't available from Korg or Korg parts stockists, although it might be worth searching eBay from time to time for spares. An entire SP250 was recently sold for less than the list price of a replacement board. The good ...

SP250 with damaged amp board

Hi, can anyone please help? I bought a Korg SP250 on Ebay sold as no power parts only. It was in great condition, used as a church piano, looks like new. I opened it up and was surprised to find the amp board was badly damaged. I think someone has yanked the keyboard off its stand while the audio ...
