... i had are gone. Replaced all tantallum caps with electrolytic ones. Also
the sound quality improved a little (less noise, somehow cleaner sound).
Recommend this 'mod' for all owners of this old but wonderful synth card

boards made by Yamaha these days (yes, they still exist) doesn't have the
QS300 compatibility mode anymore.
