IMHO, use carbon comp.
carbon comp for R3, 9, 10?
What about non inductance wirewound resistor for R2, 4, 8, 11 and Vishay naked for R15 and 16?
You are really set on using wire-wound, precision resistors. I suppose you should try "A-B" test and see what you think, between WW and carbon comp.
But the value of carbon comp will drift.
Slight drift really won't matter to a tube that is single-ended, cathode-biased.
But, go with what you want to do. It's DIY. No hard and fast rules. If you run into harsh results, perhaps due to instability... consider trying those "primitive" carbon comp resistors.
There are a ton of vintage equipment running with old school CC resistors. Some sound pretty darn good.
Post your experiences.
