Rhodes Mk2 88 Issue

The Rhodes has always held a sweet spot in my musical career. This beast still has issues so, forever trying to tweak this beauty. Oddly enough a few midrange notes just 'choke', thunk? or whatever you call it.
Happy to listen to professional wisdom here.
Recorded in my studio, INRoK Studios , Sydney Australia. Signal path is
Rhodes 88-Avion Retroflyer, Neve console to CUBASE Pro.
No EQ, slight reverb only.
