I had my 01/Wfd for 17 years and never had a whine until I replaced the entire LCD backlight last year. I even tried the “reverse polarity” trick with no success. Should I replace the inverter?

Hi Paul,

the original part is a “standard” 100nF ceramic capacitor, usually ranging up to 50 volts or more. It seems that J-man replaced it with polyester types because he didn’t have any other parts at hand. The maximum voltage is much less critical than with electrolytic capacitors, 25 volts or more will be perfect.

thanx a lot Hajo! ..at last one question: the small polyester capacitors C102 and C103 with 0.1µF (in parallel with C100 and C101 .. just look up at the posting from j-man @ his 01/RW..) ..: how many votage they shoult have? ..also around 25V like the C100/101 with 100µF?

many thanx!

Hi Paul,

18 or 22 ohms should both be an appropriate replacement, as the original value is 20 ohms.

I need to replace the R78 of my 01/RW. It’s a 22 ohm one? ..or I’ve better to take something else?

best regards!

Hi Angel Sing, try these links on how to initialize the 01/W and use the “preload” function: http://www.sweetwater.com/sweetcare/ts/detail.php?Index=16001 http://indra.com/~cliffcan/01faq.htm Regards, Hajo

I own a KORG 01/W ProX, I am only interested in one sound and one sound only and that’s the Grand Piano sound. The guy I bought it from programmed it with a bunch of layered voices and I can’t figure out how to remove all those layered voices, I’ve tried downloading to users manual and I tried resetting it back to the default settings, back to how it first left the factory, but I am totally clueless. I can’t even find the Grand Piano voice, I’ve looked in both banks A & B, but out of 256 voices or however many voices there are I just didn’t see Grand Piano, but I have a feeling it’s hiding in there somewhere. So, please help me with my KORG 01/W ProX – please. Thanks.

Hi Peter,

the german translation is “Sicherungswiderstand”. My search for a replacement part ended with the conclusion, that SMD type fused resistors are expensive and/or only available in large quantitites.

Does anybody have the exact part number of the “fused resistors”? Or what is the “german” term for it?
