I'm with Andrew here. The rev-test isn't the only way to determine if a servo is failing or has failed. It shows if there's a loss in vacuum, which the servo would introduce if the rubber is punctured somewhere. But as far as I understand how these work, if the booster valve is stuck closed you'd have no brake assist *and* no loss in vacuum. Just a theory, but that's where I'd look.

ps: beautiful car!
