Subject:Hammond XB2 problem!

Hi I'm new here! Please be good with me....

A member of ComboOrgan group send me here. As my problem is kinda digi.

I have a problem with a Hammond XB2.I bought it very cheap with scratchy drawbars and noisy notes, hoping to fix it and keep it for personal use. But, ouch it's digital. Don't have so much experience with this. I have repaired some analogs but my knowledge is poor with digital organs.

I have checked the PSU and the analog preamp stage but everything is fine (hope so). With a scope I checked the output of the DAC and the noise is there until the output.... Don't know how to check the digital section.

One more thing that I did today is that I checked with a scope the PSU and there is some noise at the lines around 40mVp-p. Is this normal? Wherever I check with the scope have this noise. Even at the ground! :-/

Please help! It's a great organ and I'd like to bring it back to life... Thanks in advance.
