Art Audio Vinyl Reference Phono Preamp

I would like to have V-cap upgrade of the preamp.
Anybody know the contact information for the upgeade?
I know it has been a long time.  If you still have the unit and are looking for upgrades we can help.  I am the new distributor for Art Audio and am doing my best to reach out to folks who may have had issues in the past few years.  

Best regards
