For this I would be happy using 1/2 watt metal film resistors. (1/4 watts would probably do as well) Get the ones that have 1% tolerance. They shoudn't be to expensive also now they come in the same size as the old 1/4 watt carbon that had a 20% tolerance.
Just for a better quality result I would use multimeter to match the resistors when there are things like voltage dividers etc where the two resistors have the same value. Eg Such as R# and R4 in Fig 4. This will help minimise any offset due to the resistors. EG the 6k8 that feed the phantom power to the microphones.
Just remember that he hasn't shown the power supplies to the IC's so you need to check the specifications. Also make sure you look at his page on the power supply http://sound.westhost.com/project30c.htm
Are you going to make this up using his PCB's ?
Before you get carried away with this project ensure that you can still get the parts or an an equvialent.
