Hi Tpmi
I was surprised that you were glad to see carbon screen resistors - unless you meant that sarcastically
As always, screen resistors should always be replaced by flame-proof types and preferably the value increased to 1k to protect the tubes, as TUT pointed out decades ago. Most manufacturers have followed that advice since 1995. TUT specified using a 5W wire-wound to assure that the new Rs would be flame-proof. Small amps can use a 1-3W metal-oxide type provided it is flame-proof - not those red "flame resistant" Philips resistors, which will actually burn quite easily.
Have fun
