I'm glad to hear that your CP290 is on the air again. At some point you might
want to do some preventive maintenance by replacing the electrolytic capacitors
in that unit.  My CP290 is 1985 vintage and I had to change the capacitors back
in 2001. Check the date code on the capacitor labels.  There are six to change
and they're not expensive. I think all are radial, 85 degree C units.
