I've just been through the original TR-909 service manual and it looks like all of the applicable mods have been already been applied to the BOM.

One less thing to worry about.

the voice changes would be subjective, some prefer the older serial sounds.

toms would changed in attack and the rimshot sound too .
but i like the Rimshot from the last series much better . ( what this nava clone have. )
tr-909 service pdf file can u reading online . which parts on the mainboard changed .
