The amplifier circuit/transformers combination and construction style would make 80% of the sound. Parts would contribute another 20% or so. Active parts like tubes would matter more than a resistor. However, in a single ended 300B circuit design, anything matters. Even different resistor or wires would change the sound when using with a high end system. Voicing the amplifier would takes more time and cost more than solder the amp togather.
Tube rolling is cheaper to modify/upgrade the sound performance, but only to a small margin. The foundamental charactor of the circuit is still there.
