In analog electronics it's in fact mostly noise. Doubly so if there's a protoboard involved.

This the first working prototype of an ultrasonic to audio range heterodyne down-converter I was working on last week (I had some time for playing with this since I was waiting for the Galaksija motherboard to be manufactured).

I just hope that all the white noise I'm getting from it is in fact coming from bad connections between components and the protoboard and not from the opamps themselves.
