Default KSA-50S Krell

Wondering if anyone has experience working on this amp. Two zener diodes d17, d4 are shorted and a Tantalum cap is blown near the -18v reg on one of the output board.
Is there a chance that just these are the only components that are bad or do I have to dig deeper? Are there any scematics available for this beast? Any help would be great

There are various subtle differences in schematics over the years of it life, I think you have to see what year it was made and then ask the guys if they have a diagram.
