I believe circuit topology comes first, so I am not keen on using exotic components in building my F2.
Resistor rating - please refer to the document in FirstWatt download. I only use industrial grade stuff. For DIYer, Digikey can be a good source.
Once you build it using standard components, I believe you got the majority of the performance level set. Playing around with components are then more of a personal taste or choice.

Puffin said:I have bought some F2 boards in the group buy.
I want to get this amp right and use good quality and correctly rated components.
I would appreciate peoples views on which makes and type of resistors would be best suited to the F2.
Metal film resistors are a good start where possible.
Buy the rest from a high class distributor.
Keep away from ebay !
toufu said:By the way, what should the voltage rating be for the caps?
When properly loaded fromthe 24v power supply, the onboard votage of the F2 is ~20v. I think the L1 brings the V down. I would feel fairly safe with 25v ones.
