Because of the age of these units, I think it's imperative to have a qualified tech check out the components before diving in. I've bought four V76s in the past five years and every one of them had to have some components replaced before it met specs, and in one case the entire unit was rebuilt by Oliver Archut at TAB Funkenwerk. You may be best off buying a refurbed unit directly from Oliver or from Dave Marquette, who also does fine work with the V series Teles. And by all means when you do get a V76 make sure you used ramped phantom power to protect the transformer. Oliver suggested a simple mod that's probably archived on his guest moderator thread on the REP site. As far as the cost of repairs, Oliver does a complete refurb for $450, well worth the money. What is your dealer asking for the unit you're considering?
