ARC SP8 valve positions and tube rolling question...

84.64.244.30

Hi all,

Just a quick question: I know V1 and V2 are the phono and V3 and V4 are the line stage valves: if I am trying to do some tube rolling to see which ones I like where, am I correct in thinking if I am playing a CD then V1 and V2 are not in the sonic loop, so I can just go about changing around V3 and V4 to see if I can hear any difference between tubes?

Also, are all 4 valves used when playing vinyl?

I'm just trying to minimise the number of valve permutations I may have to keep changing....

Cheers,

Fraser
