Modern equivalent for this 1980's capacitor?
Based on the color code (assuming all three bands are red and assuming it's a cap from the designator on the PCB), that's a 2.2nF MELF capacitor. 

See also the photo in this question which shows some similar leaded parts. 

The similarity of body color to the resistors is a bit disconcerting though, I suspect it might not actually be a capacitor, but there is no way to be sure without more information (or by measuring a good one).
