Need Schematic for a Dynaco Sca-210R

I own a rather rare solid state integrated amplifier, the Dynaco Sca-210R and am looking for the schematic. Might anyone own a copy that they could share/sell or direct me to a party that might have one ? Thank you.
I don't have one, but I would try to contact Van Alstyne or Joe Curcio. Curcio concentrate mostly on the Dynaco tubed products, but he may have access to the manual (or at least know someone who does). I already checked, and it's not there.
I was thinking of picking one up , how does it sound and when was it made ?
