Enough power?

Would a scott 390 receiver sufficiently power ads 1290 speakers?
No direct experience with your two components. But the Scott is rated at 120W into 8 Ohms and your speakers are rated at 90db 8 Ohms, so it should work assuming both are up to spec.
Yes, it will easily power those speakers and the combination (if in proper working order) should produce excellent vintage sound.
