I read that thread but those changes would void my warranty so I would rather not do that at this point. I have found tube rolling to make a pretty big difference but I would like to understand better what role each set of tubes plays.
Cary PH302 MK II Tube Question
The phono pre takes 4 6SL7s. 2 are meant for the RIAA EQ and amp gain stage and buffer and 2 are for the Head amp. Can someone explain what the head amp is? The unit doesn't drive headphones so I have no idea what that is for.
On a related question, which pair are more critical to the sound? While I have a quad of Mullard ECC35s, I don't have the quad of TungSol 6SL7s so if I wanted to roll a pair in which position should I put them in? It is my understanding that the pair closer to the rear are the RIAA EQ tubes and the ones further from the rear are the head amp.
Any guidance would be appreciated.
