I have a LS100 with the optional tube phono stage. If I am not using the phono stage, do the phono tubes still have use or do they only come on if you have the OPT input selected?
I have quite a bit of time on the actual unit, but haven't really used the phono stage that much, (I have 3 other seperate phono stages). So if the 5AR4 and the 6SN7 tubes of my LS100 have say 1000 hours on them, do the phono tubes also have that much?
I'm thinking that maybe the phono stage itself only has power to it when you select the OPT input, but maybe not, that's why I'm asking.
Thanks!!!
