Suggest you start your rolling journey with the input tubes (small signal tubes). The input gain stage has the most influence on sonics. Next, the driver aka phase inverter tubes, have some influence on the sound.
Rolling the rectifier tube can have a very audible effect on the sonic signature of the amp.
I'm a believer in using NOS tubes from a reputable dealer.
