It's an RIAA phono preamp, for a record player. So it's really high gain, and I think the spec'd 2% tolerance caps are actually important because a 5% difference might be like 1/2 decibel or more of difference, just a guess. Film caps are always used in audio when possible, but I'm not sure what difference there is between polyester vs. polypropylene.
This is the circuit.
