New tubes for Cary 303T


Any recommendations for changing tubes in Cary 303T?

I now have the stock tubes, but would like to try a warmer alternative where I can hear a bigger difference when switching from SS to tube output.

My favorite Old Stock 12AU7 is the Amperex made in Heerlen Holland around 1960. These are truly great especially if you can find real/honest 7316s at a decent price. I also like the Blackburn Mullard tubes for their rich warm tone. I have heard read only really good things about the current production Gold Lion as suggested. Hope that helps . The Heerlen tubes can get very pricy.
