[sdiy] Korg X5D

[THOMAS, Mervyn]

Morning all...


Does anyone know anything about this beast? I just bought a dead one very
cheap on ebay. The reviews I've found give it a good report so I'm gonna try
and get it going rather than break it up for the parts (which was my
original plan). Haven't been able to track down any schematics on the web
though. Does anyone know if the owners manual has schematics? cos I've seen
these for sale on the web and they're still available from Korg.

Subject: RE: [sdiy] Reticon R5101..need one or replacement


Hi,


This morning I just stumbled across my ECG master replacement guide. So
I had a look at it. Under R5105 I only found a replacement for a
NPN-Transistor.
But they have two BBDs:
ECG1641 8pin-DIL, VDD=15V,VGG=-14V 1024 stages delay, from 5.12 to 51.2 ms
(Clockgenerator chip: ECG1639)
ECG1642 14pin-DIL, VDD=15V, VGG=-14V, dual channel delay (2 x 512 stages),
PMOS, up to 25.6ms delay.

Maybe this is of help

Regards,
Alex
